Can someone please point me at ppc64 xmon debugger usage /
documentation? I've had little luck finding info on-line.
Thanks in advance,
Steve.

The help output from it is pretty much all there is.
You might have better luck asking on linuxppc-dev@ozlabs.org though
(adding as Cc).
There's also an old writeup at
http://mbligh.org/linuxdocs/Kernel/DebuggingPPC64 for the very basics
of digging through a crash. Some of it is likely out of date by now.

A good trick which the help output doesn't mention is that % and $ are
special in input, so you can do:
0:mon> di %pc
disassemble instructions at address pointed to by register PC
Other regs are eg: %lr, %r1, %r12.
And it works with di, d and other commands.
Also:
0:mon> di $.xmon_register_spus
disassemble instructions at address of symbol .xmon_register_spus.
