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":

This bug is fixed in 2.4.

Aha!
Anyone working on backporting it to 2.2.21?
Alan?

That's unlikely: the improvements in smp locking are what 2.4 was all about,
so "backporting" them is basically reinventing 2.4.

2.2 does not support VIA SMP, its probably not a good kernel to choose for
the buggy VIA chipsets either.

So ServerWorks (re: his Asus CUR-DLS) is right out as well?

Serverworks I don't know. I've got reports of serverworks SMP working perfectly
well in the 2.2 tree so I don't know what the full story is there.

This board worked fine for several months under 2.2.18
I then upgraded to 2.2.20 yesterday and noticed this problem
for the first time (I didn't try 2.2.19 on it)
I still have the full 2.2.18 installation (I did the 2.2.20
installation on a separate SCA harddisk) so I can easily
switch. To see if it's a hardware problem I already switched
back to 2.2.18 once, and the problem went away.
Under 2.2.20 I have to boot with "noapic" to have it running
smoothly.
So if someone wants me to try or test something, just send
me a short note.

Does 2.2.19 work ?

I was afraid you'd ask... ;-)
I skipped 2.2.19 and went from 2.2.18 straight to 2.2.20
(This is our fileserver, so it's not that easy to find a
time slot to reboot this machine...)
But I will try it today.
