Hopefully, future versions of gdb will have a nicer interface for this,
but currently you can do:

	ps -axl -O paddr -N ... -M ...

and note the the last 6 digits of the proc addr. Prepend `0xf8' (probably)
to these digits, and present them to gdb:

	(kgdb) proc 0xf8aabbcc

This will set the process context, and you should be able to see the kernel
stack using `bt'.
