Yeah, that makes complete sense now. "DAR" and "300 trap". I should have 
seen it immediately.

Glad you see it our way. Want a job at IBM?

and here's what ppc64 prints out:

	Oops: Kernel access of bad area, sig: 11 [#1]
	NIP: C00000000008D7C4 XER: 0000000020000000 LR: C000000000086F70
	REGS: c00000007a43b7f0 TRAP: 0300    Not tainted
	...

And I'm sure it's clear as glass what that's all about.

Yeah it needs to be made clearer. We are also missing a dump of a few
instructions around the fail, especially useful when you dont have the
vmlinux or the fail is in modules somewhere.
