I just noticed the following events in my system log:
Jan 3 14:03:39 mercury kernel: APIC error on CPU1: 00(02)
Jan 3 14:03:39 mercury kernel: APIC error on CPU0: 00(02)
Below I've listed the CPU/APIC-related parts of my system start-up.
This kernel is not patched with anything; it's just a generic v2.4.17.
I didn't notice any problem in operation when these events were logged.
Looking at the older logs I see that I got the same set of events on Dec.
8th, so I guess that rules out any 2.4.17-specific changes as a culprit.
Also, I wasn't updating the CPU microcode (see below) on Dec. 8th, so this
can be held blameless as well.
Please let me know if I can provide any additional info needed to diagnose
this error.
Thanks.
