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 v3.0.3 +
http://www.spinics.net/lists/linux-wireless/msg74377.html
(see http://git.pengutronix.de/?p=mkl/linux-2.6.git;a=shortlog;h=refs/heads/wireless/rt2x00/v3.0.3)

With the patch the oops is gone, but after a few hours it fails with:

The vendor requests 0x06 and 0x07 keep failing with some rt2x00usb_regbusy_read.

First of all, the best way to get rt2x00 support is write to
(moderated for non-subscribers) list users@rt2x00.serialmonkey.com

We have now wireless-testing applied version of that fix (3 -patches):

Looks there is something wrong at USB bus. Perhaps this could be debugged
using CONFIG_USB_DEBUG and friends. Eventually look at vendor driver to
check if it does not do some quirks regarding usb bus could help.

As workaround I would try nohwcrypt module option.

Seems the best is to try to reproduce with a different usb host controller.
