With kernel towo 3.5-10 installed I'm getting the following during boot.
BUG: using smp-processor_id() in preemptible [00000000] code:powernowd /3185
Boot continues to the desktop. Doing CTRL-ALT-F1 in the desktop goes to tty1, prints the above BUG message and hangs. Only a hard reset allows a reboot.
The bug doesn't occur in earlier kernels and googling reveals this bug has has not been uncommon in the past.

Oops. Looks like this may not be a kernel bug because this morning's boot into 3.5-4-towo.1 has the same BUG message.
Could someone please move this topic to the software section (see below).
I've purged powernowd and the BUG report seems to have disappeared although the CPUs still seem(?) to be having their frequencies controlled.
I notice in the syslog that powernow-k8 is mentioned along with the 4 available frequencies available to my CPS.
Could anyone tell me if this means powernow is now part of the kernel?
If so this could mean that I was correct to purge powernowd.
Moved as requested (dibl).
powernow-k8 module was loaded so I can only assume that the powernowd package was interfering with it.
Now problems now so I'm closing the topic.
