This was the same patch you proposed a month or two back, right? I got a copy of this error report, but it wasn't at all clear what the cause of the problem was, so I haven't suggested anything. Maybe the patch for your problem will help... I also haven't done anything for your particular problem. In fact, there was a whole list of about 10 items that ought to be fixed I went over with Johannes, and I haven't started on any of them. There were 4 or so small patches I sent in, but they haven't been applied yet -- Greg is still waiting for Johannes to give the okay. (They were pretty minor, except one that fixed a nasty bug in the queueing code for control messages.) My feeling is that a reasonably large change may end up being the best thing to do. In particular, we probably only need to have one QH per queue, instead of one for each URB. But it'll be a while before that stuff gets done.
