Hi,
My laptop running -CURRENT (with source from yesterday morning), just
panic'ed - and I am able to reproduce the problem.
First of all, on boot I disable ACPI as it does not work on my system.
# dhclient ep0
on which the system crashes, here is console output:
<snip>
Fatal trap 12: page fault while in kernel mode

If I do the same operation when booted up with ACPI enabled, the machine
just restarts..
Let me know, if you need more information.
