I'm marking this as a duplicate of bug #1217189. I don't find @timg-
tpi's comment very reassuring. This is a critical bug for the LTS
release.

@timg-tpi: Have you seen bug #1217189, involving machine lock-ups due to
this error, probably triggered after heavy swapping?
Do you have any suggestions as to why regular raring users seem
unaffected by this bug (or at least they're not complaining)?

You received this bug notification
might be related to bug #1217189 which raises the possibility of hard
machine LOCK-UPS due to zram errors. I've had several such lock-ups on
precise after the most recent linux-lts-raring updates (and none before
that) that seemed to go away after disabling zram.
** Changed in: linux (Ubuntu)
There will be a linux-lts-saucy shortly after 13.10 is released.
