Bug Description
When using my USB Ralink wifi dongle I am seeing an occasional but fairly easy to trigger crash. Basically all one has to do is plug it in, use the network connection and wait. It will crash, maybe it will take minutes, maybe it survives a day but eventually it will crash. Always with the same stack trace.
I have attached two photos of the screen displaying this, hopefully it will prove useful in resolving the problem.

Hi David,
are you still seeing this trace with a current 2.6.37 kernel and with a current bleeding edge compat-wireless[2]? If so this bug will likely see a lot more attention upstream, e.g. at the rt2x00 project mailing list[1].
