Christopher, do you think there's any chance the upgraded BIOS from bug
1157909 would affect this issue? If so, I can use the default 12.04
kernel instead of the latest and test it out.

My thought is that if the 12.04 kernel triggers this bug, it'd be best
to fix it, especially since 12.04 is an LTS release and supported for
the next 4+ years. It'd be bad if everyone with certain Thinkpad models
that installs 12.04 is affected by this bug, especially since at least
in my mind LTS versions are supposed to generally be more reliable.

Thanks!

Title:
  [Lenovo Thinkpad T430u] randomly locks up/freezes

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  System randomly locks up completely.  Screen is frozen, system is
  completely unresponsive.  No key combos have any effect (Ctrl-Alt-Del,
  Ctrl-Alt-Backspace, Ctrl-Alt-F1).  The only thing that works is
  holding down the power button until it turns off.

  I tried Alt + SysReq + REISUB (http://askubuntu.com/a/36717/18665)
  when it locks up, but it has no effect either.

  It normally does it about once a day, but this morning it locked up 3
  times in the past hour or so.
