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_
[ 1373.832108] brcmsmac bcma0:0: phyerr 0x1, rate 0x1414
[ 1373.832122] brcmsmac bcma0:0: brcms_c_
[ 1373.960962] brcmsmac bcma0:0: wl0: PSM microcode watchdog fired at 1325 (seconds). Resetting.
[ 1373.960979] brcmsmac bcma0:0: wl0: fatal error, reinitializing
[ 1373.962829] ieee80211 phy0: Hardware restart was requested
Fixed either by reboot or turning wireless hardware switch on and off.
