Asus CUV4X-D, 2.4.3 crashes at boot

["Simon Garner" <sgarner@expio.co.nz>]

Hi,

I've compiled kernel 2.4.3 on the following RH7 system, and I'm now getting
random crashes at boot, during IO-APIC initialisation. Random meaning that
sometimes it boots fine, other times it doesn't, and it hangs in different
places (but always around IO-APIC stuff). It almost always hangs after a
cold boot - if I do a Ctrl+Alt+Del then it will usually boot up OK.

System: Asus CUV4X-D motherboard, Dual P3 800EB.

The last thing I see on the screen when it hangs is, for example:



CPU1: Intel Pentium III (Coppermine) stepping 06
CPU has booted.
Before bogomips.
Total of 2 processors activated (3207.98 BogoMIPS).
Before bogocount - setting activated=1.
Boot done.
ENABLING IO-APIC IRQs
...changing IO-APIC physical APIC ID to 2 ... ok.
Synchronizing Arb IDs.
...TIMER: vector=49 pin1=2 pin2=0



Sometimes it gets a little further, but it's always somewhere near the
IO-APIC
stuff.

When it does boot, I get:



CPU1: Intel Pentium III (Coppermine) stepping 06
CPU has booted.
Before bogomips.

Any ideas?
