That can't be, I have no xen modules in use and this commit only
changes xen-blkback/blkback.c

Maybe it's easier to see what the first commit between 3.10 and
3.11-rc1 is that introduces an issue.
I could probably bisect this too, but make-kpkg takes an awful lot of
time because it always seems to rebuild everything - is there a way
around that?

This one won't wake up anymore, probably a kernel panic but the display
won't get initialized again, no network and nothing written to the log.

Nothing there yet, may try again later.
