I can probably do so, but I'm sure Hunter will be on this eventually too.

Also, I saw that you mentioned something about commit 55f6153d8cc8, so I
reverted that commit, rebuilt the kernel, and tested, but I forgot to apply the
previous debug patch.  The TRBs problem doesn't appear to be present anymore
and I haven't run into any hard lockups within the ~24 hour period that it has
been running for so far.  Although, I'd like to run things with that kernel
build for a while longer before saying anything definitive, and I think that
some of the changes themselves within that commit are justifiable (but what can
I really say; I'm way too new at this), so changes likened unto those in this
newest patch appear to be a better solution to me.  I'll just build the most
recent kernel release with this patch for another device.
