The intel wireless aspect of this kernel panic might be a red herring -
the machines panics most times it's booted, with or without the iwlwifi
drivers blacklisted.  The panic usually occurs a few seconds after the
lightdm login screen appears (Which happents to be about the same time
the wireless associates, usually).  After a series of hard powerdown and
restarts the machine boots without panicking, but this seems to be
enssentially a random thing, it panics more often than not.

Title:
  kernel panic when intel wireless card associates

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Since this morning, following an update, my machine kernel panics as
  soon as NetworkManager connects the wifi, or if I press the key to
  power off the wifi card.

  Blacklisting the wifi modules (iwlwifi and iwldvn) and using a USB
  wifi card instead results in a stable system.

  I'm on a Lenovo Thinkpad Edge E130, running Trusty, running 3.13.0-24-generic, and the intel card is, according to lspci, an Intel Corporation Centrino Wireless-N 2230 (rev c4).
