Hi
I've been getting this panic at boot time for last few weeks. The
last kernel that works is of around Wed Jan 7 15:23:38 SAST 2004.
Random datapoints:
Gigabyte 686DLX motherboard with 2 PentiumII CPUs
I've noticed that ACPI has been working more and more poorly
with this motherboard.
I think this is related to ACPI brokenness because the working
kernel panics in exactly the same way if I set hint.acpi.0.disabled="1".
Here's the panic message. Sadly there is no crashdump.
I have time to try things and do more debugging on request.
Ian
