Ok, thanks. If pinging doesn't work, bribery can be quite effective with
hardware guys :)

Indeed, that hack didn't help me and I'd rather not commit it if it only
partially fixes the problem. A better bet might just be to go with your
original approach and see how many bug reports we receive. That might also
help us narrow down the problem, but it's your call.

In the meantime, I pushed what I think is the latest drop of your series to
a new branch on kernel.org:
