[rt2x00-users] rt2800usb stops at random

Tried with the patch on 3.5 rc2-1. It seems that the patch fixes the
problem at the startup of the interface but then after two hours or so of
traffic it stops receiving anything.
According to the patch creator
problem seems to be the following:
1.Much rxdone_work is registered into work_queue by rt2x00_usb_kick_queue
of initialization processing.
2.Before all rxdone_work is completed, new rxdone_work starts.
3.queue_entry competes and entry which has not been ended remains in queue.
4.Since top of queue is not removed, a stole is carried out.
Is there anything I can do? Anyone can provide flow diagrams of the code in
order to debug it? Any hints?
