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.
