panic with yesterday's sources

[Michael L. Hostbaek]

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>

If I do the same operation when booted up with ACPI enabled, the machine
just restarts.. 

Let me know, if you need more information.
