Comment 0 for bug 118110

Sometimes (I still don't know why) the ipw3945 hangs and I need to reboot my Dell Latutude D820!
It seems this bug is there since a while because I found somne other reports with previous version ...

Hope it'll be fixed soon or anybody knows a workaround? Today it needed 5 reboots, thats annoying ...

Here the "dmesg" - output:
