APIC-UP related panic

Hello,

I have one reproducable panic with sources from 04. Nov when enabling "device 
apic" in the kernel.
While building OpenOffice about 1 1/2 hours after start the system reboots. 
This is absolutely reproducable. Removing device apic from the kernel solves 
the problem!
The only thing I have are these lines from /var/log/messages:
(attached the different dmesgs)
