Lock on CPU1 of a SB1000

Ferris McCormick
I'm pretty sure this is a bad CPU, but I'll post it in case it looks
familiar to anyone.  Any clues?
This is an asymmetric SB1000 (1x900, 1x750) system running
kernel2.6.27-gentoo-SB1000.  At the time of the lock, it was reasonably
as a distcc host for a large build from a U2.

Necessarily, CPU1 is the slower CPU.  I'll replace the CPU in a few
days; I don't want to bother any more today.

Thanks and regards,
