Title:
  "BUG: unable to handle kernel paging request at 000000080000003a",
  "swap_free: Bad swap file entry" and other weirdness during boot since
  3.8.0-18

Status in “linux” package in Ubuntu:
  Invalid

Bug description:
  Ever since kernel 3.8.0-18, I've been getting worrying warnings from
  the kernel during the boot process. The system ran rock solid for the
  past 2 years and continues to do so with 3.8.0-17. The problem does
  not happen during every boot, but when it does, it seems to "stick"
  for the next hours or so , i.e. rebooting with 3.8.0-18 / -19 will
  yield the aforementioned errors every time. Booting 3.8.0-17 helps and
  the system runs fine. Here is an excerpt from two dmesgs that I will
  attach in full:
