["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

James Hunt, as per http://download.lenovo.com/express/ddfm.html an
update is available for your BIOS (1.42). If you update to this, does it
change anything?

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Thank you for your understanding.

** Summary changed:

- constant wifi stalls with Intel Centrino Wireless-N 1000 (e1000e module) and error ">fail to flush all tx fifo queues"

  /build/buildd/linux-3.5.0/net/wireless/mlme.c:491
  cfg80211_mlme_disassoc+0xcd/0xe0 [cfg80211]()

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Problem seems to have happened in the last few days, possible due to
  different networking equipment in use here at UDS?

  In desperation, I shut down wlan0, rmmod'ed e1000e and reversed the
  operation. This generated an Oops and didn't fix the problem:
