In response to the instability issues I've had with LB (It's not ram -- memtest86+ ran for hours under LB with no errors), someone here suggested that there are chipset registers that are reset by the factory BIOS that LB isn't (re)setting correctly, and that LB works well right after using the factory BIOS because those registers hold their values for a while.
I'm conviced this is the case -- I have too many weird issues that can be fixed by simply flipping back to the factory BIOS, turning the system on, getting a "bad CMOS" error, then immediately powering off and switching to LB, which suddenly works again.
I'm pretty sure the DMA transfer under Linux bug (this is a chipset bug specific to some Epia models that can be fixed (in theory) with a BIOS upgrade) is exhibiting itself -- I get hard locks with the HD light on when xferring larger files. It's really easy to reproduce. I tried to lock it under the factory bios, but it wouldn't lock. After I rebooted using LB, the problem went away in LB as well. This tends to support the "chipset register remembrance" theory.
Here's the latest. The full serial caps are at the bottom, but here are the differences. I set all the kernel times to zero so that diff would work.
Differences in LB output:
Crash: Low Bond 00 High Bondc0 Setting DQS delay80vt8623 done Worked: Low Bond 00 High Bondc1 Setting DQS delay80vt8623 done
I'm no expert, but this appears to be looking for a range of usable RAM under 1M. Should the High Bond values be different, ever?
Differences in kernel output: Crash: [00000.00000] DMI 2.2 present. Worked: [00000.00000] DMI not present or invalid.
I'm not sure if this is relevant or not ...
And finally, the crash itself:

suggested that there are chipset registers that are reset by the factory BIOS that LB isn't (re)setting correctly, and that LB works well right after using the factory BIOS because those registers hold their values for a while.
Do a 'lspci -xxx' diff on the north and southbridges beween factory and LB and investigate all the differences.

Richard,
I originally posted two serial captures from a "good" lb boot, and one where it crashes. I hadn't realized it at the time, but the block of hex numbers at the top of each is a dump of the northbridge configuration space. They are identical. Going on the assumption that if the PCI configurations are the same, then the chip must be configured correctly, I must assume that the problem lies with the south bridge ... Or am I way off?
Unfortunately, LB doesn't dump the south bridge to serial -- I'm working on changing that =)

I'm conviced this is the case -- I have too many weird issues that can be fixed by simply flipping back to the factory BIOS, turning the system on, getting a "bad CMOS" error, then immediately powering off and switching to LB, which suddenly works again.
Check the CMOS battery voltage. If it's low the CMOS will loose a bit or two over time. Ran into that problem years ago on a 286 mb.

I measured 3.08 V, using a Fluke. Since it's a CR2032 battery, it's good to go.

One further observation re this locking up is that you seem to be using fast memory compared to the speed of the chipset. The debug output:
CAS Supported 2 2.5 3 Cycle time at CL X (nS)50 Cycle time at CL X-0.5 (nS)60 Cycle time at CL X-1 (nS)75 Starting at CAS 3 We can do CAS 2.5 We can do CAS 2
tells me that LB has spotted memory rated as DDR400, and is consequently trying to use it with a 'tuned' CAS setting of only 2. DDR266 usually works at CAS of 2.5 or 3. It 'MAY' be the case that working the chipset / memory interface at this 'tuned' setting is marginal - OK under memtest, but as soon as you have other bus masters trying to access the memory as well then you get problems.
You could test out this hypothesis by forcing CAS of 2.5 or 3 in the memory detection routines. Should be easy to do since the code starts out with 3 and then decides if it could do better. Simply comment out those tests.
Or try it out with DDR266.

In response to the instability issues I've had with LB (It's not ram -- memtest86+ ran for hours under LB with no errors), someone here suggested that there are chipset registers that are reset by the factory BIOS that LB isn't (re)setting correctly, and that LB works well right after using the factory BIOS because those registers hold their values for a while.
I'm conviced this is the case -- I have too many weird issues that can be fixed by simply flipping back to the factory BIOS, turning the system on, getting a "bad CMOS" error, then immediately powering off and switching to LB, which suddenly works again.
I'm pretty sure the DMA transfer under Linux bug (this is a chipset bug specific to some Epia models that can be fixed (in theory) with a BIOS upgrade) is exhibiting itself -- I get hard locks with the HD light on when xferring larger files. It's really easy to reproduce. I tried to lock it under the factory bios, but it wouldn't lock. After I rebooted using LB, the problem went away in LB as well. This tends to support the "chipset register remembrance" theory.
Here's the latest. The full serial caps are at the bottom, but here are the differences. I set all the kernel times to zero so that diff would work.
Differences in LB output:
Crash: Low Bond 00 High Bondc0 Setting DQS delay80vt8623 done Worked: Low Bond 00 High Bondc1 Setting DQS delay80vt8623 done
I'm no expert, but this appears to be looking for a range of usable RAM under 1M. Should the High Bond values be different, ever?
Differences in kernel output: Crash: [00000.00000] DMI 2.2 present. Worked: [00000.00000] DMI not present or invalid.
I'm not sure if this is relevant or not ...
And finally, the crash itself:

Nick,
When I bought that ram, I was looking for "low profile" ram so that everything would fit into my tiny case. That was either the only speed they had or the lowest speed ram they had in low profile. I have a lot of ram lying around -- I can try different ones.
One question -- why would this problem be 'fixed' by allowing the Factory Bios to set some registers? Or are you referring to the DMA lock issues?

One further observation re this locking up is that you seem to be using fast memory compared to the speed of the chipset. The debug output:
CAS Supported 2 2.5 3 Cycle time at CL X (nS)50 Cycle time at CL X-0.5 (nS)60 Cycle time at CL X-1 (nS)75 Starting at CAS 3 We can do CAS 2.5 We can do CAS 2
tells me that LB has spotted memory rated as DDR400, and is consequently trying to use it with a 'tuned' CAS setting of only 2. DDR266 usually works at CAS of 2.5 or 3. It 'MAY' be the case that working the chipset / memory interface at this 'tuned' setting is marginal - OK under memtest, but as soon as you have other bus masters trying to access the memory as well then you get problems.
You could test out this hypothesis by forcing CAS of 2.5 or 3 in the memory detection routines. Should be easy to do since the code starts out with 3 and then decides if it could do better. Simply comment out those tests.
Or try it out with DDR266.

I've dived into the northbridge/southbridge fixup code in LB, in response to Richard Smith's suggestion that I check for differences in the PCI configuration space between the Factory and LB boots. I've learned a lot about how PCI works, but I've got a long ways to go.
Here's what I've noticed:
Some of the data in 0x00 --> 0x3f is different. I'm guessing this isn't a big deal, since (in theory) the kernel knows how to deal with the "standard" PCI registers, and some of them (IRQ/IO port settings) can/will be different. Is my assumption correct?
Some of the values in the higher addresses are different. Some of the values are placed there by the PCI fixup, and many match the values found when running the factory BIOS. Oddly, some of the values placed by the fixup are different, but the 'lspci' output is the same. For example, the fixup calls:
pci_write_config32(dev, 0x88, 0x00000002);
However, the value in the configuration for lb and factory after boot is:
Factory: 80: 0f 65 00 00 80 00 00 00 _03 00 d6 0c_ 00 00 00 00 LB: 80: 0f 65 00 00 80 00 00 00 _03 00 98 0c_ 00 00 00 00
There's a 0x03 byte in location 0x88, and the upper word is NOT zeroes on either one of them. This leads me to believe that either the chip itself changed the value, or the Kernel did.
Of course, there may be other LB code sections that put more/different values into the northbridge PCI config.
Is there anyone who can give me some tips on extracting the "magic fixups" from a factory BIOS? I know that there are probably newer factory BIOSes since LB was ported to the Epia M.

In response to the instability issues I've had with LB (It's not ram -- memtest86+ ran for hours under LB with no errors), someone here suggested that there are chipset registers that are reset by the factory BIOS that LB isn't (re)setting correctly, and that LB works well right after using the factory BIOS because those registers hold their values for a while.
I'm conviced this is the case -- I have too many weird issues that can be fixed by simply flipping back to the factory BIOS, turning the system on, getting a "bad CMOS" error, then immediately powering off and switching to LB, which suddenly works again.
I'm pretty sure the DMA transfer under Linux bug (this is a chipset bug specific to some Epia models that can be fixed (in theory) with a BIOS upgrade) is exhibiting itself -- I get hard locks with the HD light on when xferring larger files. It's really easy to reproduce. I tried to lock it under the factory bios, but it wouldn't lock. After I rebooted using LB, the problem went away in LB as well. This tends to support the "chipset register remembrance" theory.
Here's the latest. The full serial caps are at the bottom, but here are the differences. I set all the kernel times to zero so that diff would work.
Differences in LB output:
Crash: Low Bond 00 High Bondc0 Setting DQS delay80vt8623 done Worked: Low Bond 00 High Bondc1 Setting DQS delay80vt8623 done
I'm no expert, but this appears to be looking for a range of usable RAM under 1M. Should the High Bond values be different, ever?
Differences in kernel output: Crash: [00000.00000] DMI 2.2 present. Worked: [00000.00000] DMI not present or invalid.
I'm not sure if this is relevant or not ...
And finally, the crash itself:

You could try this: do the exact same test, but turn off the board, *disconnect the power connector*, let it sit 30 seconds, and then put in LB and see if it works or not.
I'd be interested to hear this result.

I have done this -- It doesn't cause the problem. I had the machine off for two days with the PS unplugged (no aux power), and the power connected disconnected from the MLB. Booted just fine after that. I think whoever mentioned the CAS setting being too fast might be on the right track, but it's weird that the factory BIOS fixes it (for a while).
WRT DMA issue:
(I only booted using LB)
Also, last night, I _hammered_ the southbridge by copying 50M files on the HD, FTPing 50Meg files, and Copying 100M files from usb stick to HDA. I ran this for several hours. The CPU heatsink got pretty warm. No crashes. Previously, just copying from HDA to HDC would crash it, or from USB >> HDA, regularly.
So I Power down, Reboot (LB again), restarted the HDA >> HDA copy and the FTP. Froze up within 10 minutes.
I'll re-run the tests tonight using the factory BIOS -- who knows what's going to happen.

There's a good chance that factory bios is bug-fixing another part and getting the programming via flash settings. This is commonly done in factory bioses. This is another part of our life that is made hard by proprietary bug-fix code.
