[Bug 557088] Re: WARNING: at /build/buildd/linux-2.6.32/drivers/net/wireless/iwlwifi/iwl-tx.c:1169 iwl_tx_cmd_complete+0x133/0x170 [iwlcore]()

I seem to be getting the same problem. There are no symptoms explained
above, so let me tell you what happens to my machine:

Occasionally on suspend and resume, Network Manager won't connect to wireless networks, and if I try to do so manually then it just says "device not ready" under the Wireless section.
This doesn't happen on every suspend/resume, and there doesn't seem to be much of a pattern to it, happens around once every 1-2 weeks I'd say (I barely ever reboot unless I have to)
Previously in the Lucid cycle I was able to fix the problem with "sudo rmmod iwlagn && sleep 5 && sudo modprobe iwlagn" and this would then make the device available again and Network Manager reconnect. I don't remember which kernel was running then, I believe this worked in -16 and -17.
However, it seems that in -18 and -19 doing the above command doesn't fix the problem, and instead just brings up the apport window to submit a problem report to Launchpad and kerneloops.org. To fix the problem under these later kernels, I have to reboot the machine and then wireless works again.

Apport suggested that I test with upstream kernels, which I'm happy to
do (I'm going to go and install it now), but the fairly low frequency of
this issue means it may be 2-3 weeks before I can say whether it's
working properly or not...
