Coreboot issues with ASRock E350m1

[Marshall Buschman]

Hello:

I was instructed to send mail to you by Carebear from #coreboot.
I have some issues to report based on the "Golden Image" I received from 
him, which was created for the ASRock E350M1.

After booting, my Linux kernel panics like this:
http://www.lucidmachines.com/coreboot/panic-lm-patched-2.6.39.txt

I should mention that this is a slightly modified 
(http://www.lucidmachines.com/coreboot/2.6.39-pci-do-fixups.txt) kernel, 
patched to enable PCI Quirks only for a specific PCI ID: the video card.
This is done so that the radeon firmware blobs can be loaded, enabling 
KMS, while not delaying my boot for 800ms.
I have not tested this specific thing on a vanilla kernel, but it does 
work perfectly on a normal BIOS.

CareBear told me to enable ACPI (and try it with the vanilla kernel), 
and it no longer panics, but he did note the following quirks:

[ 0.137098] Extended Config Space enabled on 0 nodes
[ 0.178984] ACPI: (supports S0 S5)
[ 0.289970] Unable to assume _OSC PCIe control. Disabling ASPM
[ 0.310267] ACPI: PCI Interrupt Link INTA (IRQs 3 4 5 7 10 11 12 15) *0, 
disabled.
This last error is repeated for INTB to INTH

Other issues:
* Network card is not recognized at all (works fine with stock BIOS)
* Total system RAM is reported as 480 Megabytes, actual system ram is 
4096mbytes.

The image I have does not have serial output enabled - I am working on 
getting another image compiled for better debug output - unfortunately, 
my time tonight is extremely limited, as I begin traveling tomorrow.
I will return on Tuesday, May 31st, and will be unable to return emails 
until then.

I do look forward to working with all of you on this.

Thank you!

The recent patch set may resolve the above problem:
http://permalink.gmane.org/gmane.linux.bios/66598

][ 0.178984] ACPI: (supports S0 S5)

I think this is expected because more work is needed in order to
support additional power states.

][ 0.289970] Unable to assume _OSC PCIe control. Disabling ASPM
][ 0.310267] ACPI: PCI Interrupt Link INTA (IRQs 3 4 5 7 10 11 12 15) *0,

Probably work is needed on the interrupt routing. I did not check it.

]Other issues:

We are probably missing some PCIe board support.

]* Total system RAM is reported as 480 Megabytes, actual system ram is 
]4096mbytes.

ASRock E350M1 Testing to date has used only 2GB, so it is possible
memory above 4GB will not be reported properly. On the other hand,
all usable memory below 4GB should be reported. I think the patch
set will at least get the memory below 4GB reporting properly.

Thanks,
