Subject: 2.6.24 Kernel freeze


Hi,

I'm experiencing random kernel freezes with Kernel 2.6.24.3, also -rc3 
and -rc5 (those where the one which I've tested). I'm unable to 
reproduce this bug. It sometimes occurs and usually not. Looks like it 
is more frequent with -rc3 and rc5. With .3, which I'm using since 
26-Feb, it appeared only 2 times.

Boot-up freeze (always) on Thermal Zone setup. Complete sequence:

Previously I was using 2.6.20.1 with which I didn't faced any freeze.
The ACPI message with 2.6.20.1 shows also ,,BIOS bug'':
Dec  8 19:38:32 difrost kernel: ACPI: 2 duplicate APIC table ignored.
Dec  8 19:38:32 difrost kernel: Processor #0 6:15 APIC version 20

Dec  8 19:38:32 difrost kernel: Enabling APIC mode:  Flat.  Using 1 I/O 
APICs

How can i find whether it's a Kernel or hardware bug. With 2.6.20.1 it 
works ok, so looks like Kernel misbehavior.
