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...

Hi Zaphod,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 557088

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
