Description:
The Machine is a HP DL385 with two AMD 280s in it (dual cpu, dual core
2.4GHz).  Booting the x86_64 Flight 4 dapper live CD, I get this oops on
the dmesg:

I have seen a similar OOPS on my work desktop booting dapper live CD
flight 2 (#21223)

I also see this segfault from powernowd in my dmesg, but that may be
because I tried to kill it with /etc/init.d/powernowd stop... and it
only partially died (1 cpu went back to full throttle, the other one
didn't)... so I ended up -9'ing it.
