Re: Oops in IO_APIC with linux-2.2.15pre17 on dual-pentium-III

AFAICS the sequence of assembler instructions is impossible:
    eax: 9
    ebx 801fe8cc

the faulting instruction is

> 0: 8b 13 movl (%ebx),%edx <=====
    i.e. load an integer from (%ebx)

and the CPU failed with:

Unable to handle kernel NULL pointer dereference at virtual address 00000009

but that's eax!

I doubt that you are overclocking your computer, but could you check your
power supply, cabling, cooling,...?

And check your kernel log: oops always on CPU1, or on both cpus?
What about these messages, is that common with eepro cards?
