Public bug reported:

Problem causing my wireless card to disconnect when establishing a
configuration for ad-hoc mode. Noticed it when playing around with
commotionwireless, which uses Network Manager to setup the connection.
But something seems to go wrong with the drivers.

Infrastructure (mode managed) works just as it should as far as I can
tell, both before and after this syslog entry.

Ad-hoc does seem to work when setting up manually and pinging/ssh:ing from my 
computer. I just figured I'd post a report here since syslog gave me a big 
WARNING entry (entire cutout in attached syslog.txt)
WARNING: at 
/build/buildd/linux-3.5.0/drivers/net/wireless/iwlegacy/common.c:2123 
il_remove_station+0x385/0x390 [iwlegacy]()

I'm afraid I'm not capable to understand really what the warning message
implies, so I'm not sure to what degree this is a bug or just weird
error reporting :)
