Panic while waiting on wlan0

Hi,

I am running -CURRENT on my Lenovo T410 notebook since nearly a year now 
and am now experiencing my first reliable occuring panic.  Since I am 
interested into getting more involved, I want not only to give a report 
on this, but ask for directions on how I can help to fix the issue.

The crash occurs on bad wifi reception, either on startup, if “waiting 
30s for default interface” is not interrupted, or at a later point if 
the wpa_supplicant is not able to establish a connection (mostly due to 
a wrong passphrase, which is not the case if the wifi reception is 
better).  Core.txt and the dump info are attached.

I am using git commit 71f160e0193fee45242bebeff7f1282846e83d2c.

Best regards,
