Bug Description
Hello!
Just rebooted two identical Ubuntu 12.04.1 LTS servers to set linux-image-
And got the same panic on both. Don't think it is fixed in -31.
Servers are connected to IBM3512 over iscsi with multipath rdac and ocfs2.
Here is log from one of servers:

server console was not available at this time , ssh too, although I can ping server, so I had to reset both servers.
There was no such problem with -29 kernel...
Thank you!

btw, I don't know why it is attached to pwernap, I choosed linux-image- 3.2.0-30- generic as package.
I don't know how change this :-(
