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.
