I ran 4.3-rc2 with your patch applied. The problem still happens:

I turned on all tracing. Maybe it will be useful. The easiest way to provoke
it was seemingly to run lots of other stuff, and then kill my program with
SIGSTOP, wait a few seconds, and then SIGCONT:

In this state it looks pretty bad already, overruns, Ping response errors and 
Missed
service intervals. Trying to stay in sync with which TD will be processed is a 
bit challenging here.

But can you find a "No Ping response error, Skip one Isoc TD" entry in the log 
that didn't cause any
harm, e.g. it was not followed by a "ERROR Transfer event TRB DMA.." entry, and 
continued working

If yes, then the patch helped.
