Subject: Asus A7M266-D, Linux 2.6.7 and APIC (fwd)
Date: Tue, 20 Jul 2004 22:42:16 -0700 (PDT)	[thread overview]
Message-ID: <20040720223850.C80982@sublime.winfirst.com> (raw)

I'm having what I suspect is a newbie-type problem, but I assure you I've
looked around.

I have a dual-proc server that I've recently decided to overhaul.  It's an
Asus A7M266-D motherboard.  It has been running with dual Athlon MP
1800+s, RedHat and BIOS rev 1003 for at least a year with no real
problems.

First I decided to change the OS to Gentoo.  I built the system with no
problem and built a custom kernel based on linux 2.6.7-gentoo-r11.
Everything was working great.  Then I changed out the procs and went with
dual Athlon MP 2800+s.  To support these, I needed to (according to Asus's
website) upgrade the BIOS to 1011.002 or higher.  (Latest is 1011.003, so
that's what I used.)

Now, when I boot to this custom kernel I get about 2 seconds into the boot
process before the system starts spewing constant "APIC error on CPU0:
04(04)" messages.   It stops booting at that point.

I've done a little research and it seems that I'm supposed to do a couple
of things:
	1.  Disable "MPS 1.4 Support" in the BIOS.
	2.  pass the kernel "noapic" as a parameter.

I've done both of these and I STILL get the APIC messages.  (Which leads
me to suspect the "noapic" isn't working or I'm doing it wrong at the very
least.)  My line from the grub.conf is:

kernel /kernel-2.6.7-gentoo-r11-smp root=/dev/hda3 noapic acpi=off apm=off

I've build another custom kernel where the only difference is that SMP is
disabled.  Sure enough, that works like a champ, but with only the single
CPU.

I've searched through the kernel "make menuconfig" menus and can't see
that I'm missing anything.  In fact, I can't even FIND "APIC" options
unless I disable SMP...

I'm just about out of ideas here... Any suggestions?

Thanks,
AndyB
