I have some single-processr Dell Poweredge 2450 servers that I'm trying
to move to 2.4. They have been running 2.2 SMP kernels for a while with
no problem (to take advantage of the supposed benefit of using the
ioapic).
2.4 SMP kernels seem to work fine, but using a 2.4.1 or 2.4.2 UP kernel
with CONFIG_X86_UP_IOAPIC does not. At some point before the real root
filesystem is mounted, the system begins spewing
APIC error on CPU0: 08(08)
at a high rate and eventually either locks up, or is killed by the
watchdog nmi (at which point control-alt-delete _works_)
2450's use a serverworks chipset. I don't know what other information
might be useful...
Here's an excerpt of the SMP 2.4.2 dmesg output, in case it's of any use:

I'm having similar messages, about 2-3 per day.
So far I saw these variants:
APIC error on CPU0: 00(04)
APIC error on CPU0: 00(02)
APIC error on CPU0: 02(02)
APIC error on CPU0: 02(04)
APIC error on CPU0: 04(02)
This is a Abit VP6, with 1 Celeron 433(66).
(machine passes memtest).
What does this mean?
Note that everything seems to go on fine, no hangups etc.
Balazs Pozsar.

No change (I used 2.4.2-ac9, since that was available...). (The watchdog
doesn't trip and display output, but eventually the errors stop and
rebooting is possible)
> can you run 2.4.2 with noapic?
No change, either on 2.4.2 or 2.4.2-ac9
