What are exception 700 & 901?

700 is a program check (illegal instruction or BUG_ON() statement)

900 is decrementer (aka timer) interrupt.

The 0x1000c694 address looks fishy?

That's userspace.

So you took a timer interrupt, which got into hrtimer, and something you
did caused cpufreq_notify_transition to crash, probably with a BUG_ON

This should prove quite useful! Thanks!

(which you can probably see above what you pasted, unless you don't have
access to that part of the backtrace).

This is kind of my problem. ANY suggestions (applicable to an old
world PowerMac) would be appreciated on how to get access to the rest
of the information. This thing appears completely dead at this point.

Thanks!

P.S.:  There are 2 columns of numbers:

[xxx] [yyy]

One of these is the PC. What is the other? stack?

Cheers,
Ben.
