Public bug reported:
When using the rt2800usb module provided by linux-image-3.0.0-10-generic
on an RT2770 device the system hangs after a few minutes when
transmitting a lot of data via wifi.
The system log shows kernel oopses, see kern.log.
With a self-compiled linux-3.1-rc4 the problem does not occur.
