when compiling my linux kernel i keep on recieving this message:
Warning: Clock Skew Detected Build May Be Incomplete
It seams to compile ok.
What does this error message mean?? and how can i fix it.
thanks
edwin
ps. I have only been getting this message since i upgraded to an AMD K6-2 500Mhz.
A quick run with lmbench shows we're not turning it on.
Any ideas?

I don't think our IO-APIC is enabled.. We tell it to set its ID to 2,
but it continues to think its ID is F. Here is the kernel panic:
ENABLING IO-APIC IRQs.
...changing IO-APIC physical APIC ID to 2 ...
Kernel panic: could not set ID!.
.
In idle task - not syncing.
APIC error interrupt on CPU#0, should never happen..
... APIC ESR0: 00000000.
... APIC ESR1: 00000040.
... bit 6: Received Illegal Vector
Does anyone know how to setup the IO-APIC correctly and/or know where I
can find this information (Maciej, you wrote io_apic.c, right?)?
Any help would be greatly appreciated. Thanks.

Hi:
I found the OpenBIOS web site when surfing the internet. I am
interesting in this topic. Is this project still going?

First of all, it is amazing (from our point of view) that without official
support you could do such chip init stuff so clean, how did you do this ??
As you know we are working with FreeBIOS/LinuxBIOS project, we are also
intrested in any similiar projects too. We will provide any support we
can, we will provide you the necessary documents, BIOS source/pseudo code
and hardware demo boards. As posted by Jeff Garzik et. al. on freebios
list we think there is possibility to cooperate/merge these free bios
projects.
For 540+950 issue, there are two things to note. First is that, from
business point of view, it seems that 540 chipset will not in mass
production in the near future so it would be very difficult to find
a 540 M/B in the market. We are rather focusing on 630 and the upcomming
730 series. As far as I know there is only WinFast 5400MA avaliable in
Taiwan market.
The second is that, of course we want our whole product line fully supported.
I am personally planing to have full support (i.e. boot from cold power up
without BIOS) for the following combination in the end of August (possible ??)
630/540 single chip + 950 LPC
620/530 north + 5595 sourth + 6801 SuperIO
so we need somebody to "port" or try the current implementation on these
different platforms.
Finally, it glad that you are going to visit Taiwan. If you have time,
please arrange to visit SiS and demo your work. We can show you how/what
we have done on LinuxBIOS side.

I just came across this project at SourceForge:
Talkware TIARA, an Openbios/GRUB/PFORTH composite, BIOS replacement.
Boots an unmodifed linux kernel from an IDE drive or ethernet, using
only 128kb of flash. Works with INTEL/AMD K6/2-450, SiS 530/5595 and
8139 enet. VGA & Serial console supported.
and was wondering if anybody had heard of it?
It got me thinking that maybe all of the free bios developers (this
project, freebios, openbios, linuxbios) should get together and
collaborate on features. This way there would be more developers,
which could mean accelerated development, better features, and more
testing.
Also, I would like to thank all of the people who work on these
projects now, because a free/open source bios is something we all really
need.

Hi Joerg
The only URL for TIARA seems to be

OK. Another snapshot. What worries me is the per-cpu timeslice cutoff
being listed as 0 usecs. The 'kernel bug' means that either the APIC is
not on still or that we don't set boot_cpu_id correctly; the
line is:
if (GET_APIC_ID(apic_read(APIC_ID)) != boot_cpu_id)
BUG();
Furthermore, if I skip the check, I get the following message:
APIC error interrupt on CPU#0, should never happen..
... APIC ESR0: 00000080.
... APIC ESR1: 00000080.

I cant find TIARA on the net. Can you post the url please ?
