[Bug 647302] [NEW] .169058] WARNING: at /build/buildd/linux-2.6.35/net/wireless/core.c:633 wdev_cleanup_work 0xa7/0xd0 [cfg80211]()

Public bug reported:

On this laptop, with Ubuntu 10.10 beta (though 10.04 was the same) the
wireless will occasionally crash/disconnect under moderate transfer
loads.  Then it will not reconnect without a reboot, although sometimes
leaving the wireless switch off for 5-10 minutes before turning it back
on will allow Ubuntu to reconnect.  Note that this laptop does not have
the same problem with Sabayon Linux running the 2.6.35 kernel.
