Sure thing, though that is almost exactly it. The bottom decal only has
"HP Pavilion a1630n" though there is another sticker with "Microsoft
Windows XP Media Center Edition" and it is definitely a desktop.

Title:
  0cf3:7015 [ath9k_htc] 14.04 NetworkManager hangs after 'ath: phy0:
  Unable to remove station entry for...'

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  This problem has been happening randomly since I installed 14.04.
  Today it happened twice while trying to zsync the latest iso.

  I use a TP-Link TL-WN821N wireless adapter to connect to the internet,
  which uses the ath9k_htc module. NetworkManager occasionally locks up
  to the point where any commands I try to kill it or restart it hang as
  well, and my only way out is REISUB. Right before it happens I have
  noticed twice in my dmesg:

  [  494.896048] ath: phy0: Unable to remove station entry for:
  f4:ec:38:ec:42:02 For reference that mac address is the default router
  I connect to daily.

  and then shortly after we get a kernel dump for NetworkManager:

  [  720.752078] INFO: task NetworkManager:850 blocked for more than 120 seconds.

  I don't know how to reproduce it, but it happened once on March 28
  when I installed and three times on April 2 in a short period of time.
  I will attach the dmesg I took before the last REISUB to the bug.
  Please let me know if any more information is useful, I'll try to get
  it next time it happens.
