Hi,
Updated to current bk today, and my machine stopped booting ...
I've tracked it down to the apic changes from end of last week.
cset 1.1307 boots fine, 1.1308 doesn't.
Diff of the boot messages is below. Full logs are also attached.
Gerd

Excellent. I think there may be a better patch though. Please can you try replacing arch/x86/apic.c and arch/x86/setup.c with the versions attached to this email? With luck this will both fix the problem and bring us a little closer to the Linux codebase (probably not a bad thing with all this fragile bootstrap code).
