[Bug 1215633] Re: 14e4:4727 Wireless driver fails with hardware watchdog - doesn't reset

 

Robert: The saucy kernel now has a fix for the phy errors in your logs.
I'm not sure whether or not these are related to the PSM watchdog timing
out, so please test with Linux 3.11.0-6.12 or later and let me know if
you still have issues. Thanks!

Title:
  14e4:4727 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.
