Hi Chris, thanks for the advice.  All newer kernels have worked fine.
I'm now running 3.8.0-26 without issue.

I'm not sure what the appropriate status/resolution is for "no longer
relevant" -- this was apparently just a glitch with a single kernel
version that no longer affects me.  I'd prefer to just close it and move
on.

Title:
  [Lenovo ThinkPad T520 4240] won't boot with 3.5.0-27

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  After updating to kernel linux-image-3.5.0-27-generic a week or two
  ago, my T520 4940-49U won't boot.  After 1-2 seconds, the screen goes
  blank (dark - backlight off) and the laptop stops responding.  Alt-F2,
  etc does not cause any change.  Alt-SysRq-B will reboot, but nothing
  else has any effect.  The hard disk light is not on/blinking.
  Removing the "quiet splash $vt_handoff" options from the grub boot
  options does NOT help; also adding "nofb" does NOT help; also adding
  "init=/bin/bash" does NOT help.

  Booting recovery mode for 3.5.0-27 DOES work.  Booting 3.5.0-26 in
  standard (non-recovery mode) DOES work.

  I'm unable to capture any output from a failed boot, so not sure how
  to troubleshoot further.

  Attached data was captured while running 3.5.0-26 (NOT the problem
  kernel).
