I think I've found the bad commit that introduced this bug,
dc487e5b0e9e401e9705dc4c62b9170711c68f77 thermal: step_wise: Revert
optimization. I have extensively tested kernels 3.13.0-63 and 3.13.0-64
after this commit is reverted and they boot without issue and run
without crashing. Reverting this will expose a bug in the acerhdf fan
module preventing fan control on some old netbooks.

I have attached the git bisect log.

I am unable to update the BIOS at this time. Updating with the built in
GSet BIOS Flash Updater fails with "Dell ID is not matched." and
attempting to update under FreeDOS hangs the machine with no error
message.

Title:
  Dell Ubuntu 3551: failure to boot without nolapic option

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  This laptop came with Ubuntu 14.04 preinstalled. It is a Dell Inspiron
  3551 15" Ubuntu Laptop. A problem was introduced in the linux-
  image-3.13.0-58-generic kernel update which prevents the laptop from
  booting unless nolapic is added to the grub boot command. This problem
  persists in the current latest stable ubuntu kernel linux-
  image-3.13.0-61-generic. This bug affects a clean, factory restored
  install. The system passes all of Dell's included hardware diagnostic
  tests.

  Boot fails with:

  Kernel Panic - not syncing: Attempted to kill init!
  exitcode=0x00000009

  The following kernels are able to boot without issue:
  linux-image-3.13.0-57-generic
  linux-image-3.13.0-55-generic
  linux-image-3.13.0-38-generic

  Please let me know if I can be of further assistance.
  lsb_release: Ubuntu 14.04.3 LTS

  Thanks,

  Mark Standridge
