Update:

- dmesg with hanging logs
- The hang problem seems to happen ONLY with a specific access point: c8:6c:87:a9:df:a9
  -> this is a zyxel P-2802HWL-I1, running at channel 13, with WPA2-PSK.
  -> If you need more information, just let me know
- Using wlan with the Samsung S2 as access point seems to work fine

So this is now a rather specific issue, but I guess others will run into
this sooner or later as well.

Attached dmesg with hanging processes including traceback.
