Hello,
I'm a running a sheeva plug (ARM/kirkwood) with a rt2800 USB stick in AP mode.
Bus 001 Device 002: ID 1737:0071 Linksys WUSB600N v1 Dual-Band Wireless-N Network Adapter [Ralink RT2870]
kernel is v3.0.1 +
00898a47269ae5e6dda04defad00234b96692d95 rt2x00: fix usage of NULL queue
b52398b6e4522176dd125722c72c301015d24520 rt2x00: rt2800: fix zeroing skb structure
Which is here for reference:
(http://git.pengutronix.de/?p=mkl/linux-2.6.git;a=shortlog;h=refs/heads/wireless/rt2x00/v3.0.1)
The Kernel crashes after ~1d with this oopses:
(Same oops with stock v3.0.0 and v3.0.1)

There is a patch from Stanislaw floating around that ought to fix this crash.
You can find the crash at:
http://marc.info/?l=linux-wireless&m=131279612304597&w=2
However, there is still some discussion on the patch and some more
tweaking of the patch may be required.
