OOPS with 3.9.0rc2+

[Rolf Offermanns]

Hi,

I get a kernel oops / panic with a 3.9.0rc2+ kernel (git from 2h ago) on my Sony
Vaio laptop. It happened with rc1, too.

Unfortunately I only have a screen photo as nothing gets written to the system
log.

Here is a transcript:

 Is this of any use at all? How can I help track this down? Shall I attach a
 serial console (USB only)?
