OK. Thx. (Mike & Andrew, pls let me know if you want
to be removed from the cc list.)
I heard that a few colleagues are experiencing the
same problem as well on their machines (all IBM
NetVista P-IV desktops) on FC5, which goes to prove
that I'm not alone.
(I've suggested them to try "noapic" kernel boot
parameter with FC5 kernel.)
To my untrained eyes, this is the key difference
between 2.6.IOAPIC & 2.6.no-IOAPIC in /proc/interrupts
in ref to timer (which I suspect the source of the
problem; correct me if I'm wrong):
2.6.16.14.IOAPIC: 0: NNNNN IO-APIC-edge timer
2.6.16.14.no-IOAPIC: 0: NNNNN XT-PIC timer
Here's dmesg with apic=debug:
