Bug 1252239

Created attachment 1061313 [details]
File: dmesg

since some days (weeks?) I get strange wifi reconnection problems after resume from standby. Wifi fails reconnecting, or even seeing routers. I also get full system freezes which may be related (same time period, occur after standby/when sitchin wifi on/off).

Description of problem:
strange problems recently happen when coming back from sleep
