Re: apic errors and looping with 2.4, none with 2.2 (supermicro/serverworksLE chipset)

[Chris Stromsoe]

I've rebooted with noapic and nolapic and the machine seemed to be stable
for a while.  Then I got:

Mar 24 00:27:08 dahlia kernel: APIC error on CPU1: 00(02)
Mar 24 00:27:08 dahlia kernel: APIC error on CPU0: 00(02)
Mar 24 00:27:08 dahlia kernel: spurious APIC interrupt on CPU#0, should never happen.
Mar 24 00:27:13 dahlia kernel: APIC error on CPU1: 02(08)
Mar 24 00:27:13 dahlia kernel: APIC error on CPU0: 02(08)
Mar 24 00:28:07 dahlia kernel: APIC error on CPU1: 08(02)
Mar 24 00:28:07 dahlia kernel: APIC error on CPU0: 08(02)
Mar 24 00:28:07 dahlia kernel: APIC error on CPU0: 02(08)
Mar 24 00:28:07 dahlia kernel: APIC error on CPU0: 08(02)
Mar 24 00:28:07 dahlia kernel: APIC error on CPU1: 02(0a)

I added nosmp to the lilo append line and rebooted.

noapic, nolapic, and nosmp seems to be stable.  I haven't had anything
logged in the last 2 hours.  Are there known APIC or SMP problems with
serverworks LE chipsets or supermicro motherboards and 2.4?  What are the
steps to troubleshooting an APIC problem?
