Cought this absolutely randonmly during shutdown (actually, after I booted back) 2. Not reproducible. I did a shutdown as at least 100 times before.

that's this .. if (WARN_ON(rdev->scan_req && rdev->scan_req->dev == wdev->netdev)) { John ? (Note David filed several other nvidia related bugs which indicated kernel memory corruption, so this might be a red herring).
A bit more info - the NVidia memory curruptor bugs were from one single boot. First the corruptor bug, then a bunch of bad page and related. This one if from a boot where I haven't seen anything similar. The system was running smootly without any crashes or faults and this popped up during shutdown. Likely not related but in case it helps: I did stress the system a lot as I was compiling and also copying data from one luks device to another. Then shutdown.
This problem is fixed in 2.6.37 kernel and newer, we will not backport fixes. You may consider update to F-15, or use http://people.redhat.com/sgruszka/compat_wireless.html if problem annoys you
