Yes, I'd like to see if the complete dmesg includes this line:
Local APIC disabled by BIOS -- reenabling.
Yes, the problem is known, but the solution is not.
We've seen this problem go away many times with a BIOS upgrade,
are you running the latest?
There is also a workaround here to temporarily disable the APIC timer:
http://bugme.osdl.org/show_bug.cgi?id=1269
Perhaps you can update that bug report to say if the workaround
helps your system or not.
thanks,
-Len
