Robert: Sounds like you don't know what the last kernel version you ran
which didn't have this issue? If you still have some old kernels
installed, could you try booting to them to find the last one you had
which worked?

Or even better, you could install some kernels from
http://kernel.ubuntu.com/~kernel-ppa/mainline/ to confirm that the
problem exists upstream and to see when it appeared. I'd suggest first
installing the latest (3.11-rc6 right now) and confirm it exists there,
then go back to 3.10 and confirm it doesn't exist there. Then try
intermediate -rc kernels until you find the one which introduces the
problem (odds are that it will be 3.11-rc1).

Thanks!

Title:
  Wireless driver fails with hardware watchdog - doesn't reset

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Since a recent upgrade (kernel 3.11?) my wireless has gone unstable.

  Fails every few hours, dmesg shows:

  [ 1373.827739] brcmsmac bcma0:0: phyerr 0x1, rate 0x1414
  [ 1373.827800] brcmsmac bcma0:0: brcms_c_ampdu_dotxstatus_complete: ampdu tx phy error (0x1)

  [ 1373.960962] brcmsmac bcma0:0: wl0: PSM microcode watchdog fired at 1325 (seconds). Resetting.

  [ 1373.962829] ieee80211 phy0: Hardware restart was requested

  Fixed either by reboot or turning wireless hardware switch on and off.
