--- Comment #24 from Mathias Nyman (mathias.nyman@linux.intel.com) ---
Thanks, I see whats going on now.
Some transfers that are further ahead on the ring can simply be turned to no-op
trbs by driver when cancelled. These are not added back to num_trbs_free.
This is the case when several URBs are queued for an endpoint and then
cancelled in reverse order.
I have a untested fix for this that goes on top of previous debug patch.
Can you try it out?
I'm also reworking this whole thing, but we need a small fix like this for
older stable kernels.
