Linux-2.2.20 SMP & Asus CUR-DLS: "stuck on TLB IPI wait (CPU#3)"

[Andreas Haumer]

Hi!

I'm seeing a problem with SMP Linux-2.2.20 on an ASUS CUR-DLS
motherboard. I noticed there were similar reports in the
past few months and I got the impression the problem should
already be fixed in 2.2.20, but seemingly it isn't.

We have a fileserver which was running Linux-2.2.18 without
a single problem for about 8 months or so. It has an Asus CUR-DLS
SMP motherboard with Server Works chipset and Asus Medallion
CUR-DLS ACPI BIOS revision 1009, dual Intel PIII CPU (866MHz) 
and 512MB registered PC133 SDRAM. 
There is also an Adaptec 29160 U160 SCSI controller and a 
3Com 3c905B NIC in this server.

Today I upgraded to Linux-2.2.20, and after reboot the
system became very slow, every now and then it halted for
3 or 4 seconds, and the kernel printed a lot of these
messages: "stuck on TLB IPI wait (CPU#3)"

I then rebooted, disabled BIOS MPS 1.4 support, but this 
didn't help. I had to boot with "noapic" option in order 
to get a system running in a sane way.

I have to say that this is not a pristine Linux-2.2.20
kernel, as we included the following patches:

devfs-v99.21
aic7xxx-6.2.4
sw-raid-2.2.20-A0

but the same kernel is running on an Asus CUV4X-D SMP
(dual PIII 1GHz CPU) system (VIA chipset) without any 
problem.

I found several mails on lkml reporting similar problems,
but no one reported them for this motherboard.

A few more infos from the system running with "noapic":

I would be glad if I could help fixing this problem.
