[NOTE] driver caveat

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Just a quick note because I ran into it:

[29106.600017] wlan0: No ProbeResp from current AP 00:15:f2:3d:63:97 -
assume out of range
[29106.600030] phy0: Removed STA 00:15:f2:3d:63:97
[29106.720011] mac80211-phy0: failed to remove key (0,
00:15:f2:3d:63:97) from hardware (-19)


This happened during resume, mac80211 was up already but the driver had
not resumed the device yet, so b43 thankfully detected that and didn't
try to access the hardware and returned -ENODEV from set_key().

If you've been experiencing bad behaviour with suspend this may be the
cause, instead of working around in the driver I suggest you implement
proper suspend/resume hooks in mac80211 for drivers to call ;)
