2.4.20-rc2-xfs lockups

2.4.20-rc2-xfs lockups

[Mike Eldridge]

all,

i recently replaced a pII-350 with a pair of pIII-500s in a tyan
S1836-DLUAN-GX board (440GX dual slot 1).  i'm now getting loads of NMI
interrupts for unknown reasons (reasons 2c and 3c).

i thought perhaps it was because i was running a single-processor
non-APCI enabled kernel, so i built a smp-enabled kernel.  i still get
the errors.

per information i've garnered from the linux-kernel archives, i built a
kernel with basic ACPI support as well as enabling ACPI support in the
bios.  previously, both were disabled.  no dice.

up until now, these errors have been harmless.  however, i just
experienced a hard lockup while running X.  i can only assume the NMI
errors are a result.

i'm going to build a linux-2.2.22 kernel and give it a whirl.  other
ideas i have are: try APM instead if ACPI; try a single processor in the
board.  any suggestions are more than appreciated.

following are contents of /proc/pci, /proc/interrupts, and
/proc/cpuinfo.  if any other files would be of use, let me know.

thanks in advance,

-mike

after more googling, i've found several pieces of information that seem
to suggest interrupt routing on 440GX-based motherboards is busted.

can anyone confirm this?  will booting with 'noapic' fix this problem?
am i doomed to run a UP kernel?

It varies. Unfortunately Intel won't tell us how to sort this mess out.

hrm :/

ironically, i've got another box here (440GX dual pIII-500) running
linux-2.2.20 with apic enabled that doesn't have this problem.
interestingly, the NMI line from /proc/interrupts only lists counts for
CPU0, not for CPU1.  and it's sitting comfortably at 0.

running with 'noapic' on the troublesome machine still produces NMIs and
random hangs.
