The latest proposed kernel fails even worse than my original report. The
conditions when it fails (that is when the iwlwifi module is loaded) is
the same. However, now blacklisting iwlwifi and then manually modprobing
it after logging in locks up the system such that I cannot capture the
dmesg. Before, I was able to capture dmesg after attempting to load the
module.

FWIW, I also compiled a 3.14-rc2 kernel. It doesn't have this problem.

Title:
  kernel panics with BUG

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have a Dell Sputnik 3 that I just got and upgraded it to
  12.10->13.04->13.10. On boot the kernel crashes with a BUG.  Attached
  is a dmesg output from after the loading of the module.

  WORKAROUND: I can prevent the crash by blacklisting the iwlwifi module
  and I can cause the BUG by manually loading the module.
