Thanks for testing!  The occational "tx status missed" is unavoidable
due to hardware limitations.  My patches reduce the number of them,
but more importantly they fix a few issues with TX (status) timeout handling.
(IIRC false positives in TX timeout check, and fluash would wait for
TX queue empty which would never happen without the timer to reap
the status queue.)

I tested a lot with these patches and they work stable for me, however I
must admit I'm not sure why they help in your case (i.e. why does
bulk transfer stall without these patches?).
