Yeah, not a lot to go on. That case should probably use
VM_BUG_ON_PAGE() to five a little more information, but on the whole
it's does look like just major memory corruption.

The call trace doesn't really strike me as a likely source of the bug.

Enabling slub debugging does seem to be the best idea.
