I am reluctant to agree because it happens also when wpa_supplicant is 
not running and the wifi device is turned off. A very common effect of 
this type of crash is that the JFS filesystem creates a 'stale NFS file' 
at /etc/mtab (I suppose failing to delete it), but the filesystem is 
marked as clean so I have to force a fsck to fix it (root filesystem 
won't mount without being able to write to /etc/mtab).

Does the backtrace tell anything relevant?

Perhaps we need serial console output?

I agree that the wpasupplicant is not responsible anyway.
