I am definitely seeing issues with an APC USB I have on my desktop.  I have
used this desktop + APC combination for at least 5 years now and only after
my most recent upgrade to 11.1-STABLE at r326909.  I did not have issues on
the previous 11.1-STABLE kernel at r321399, so it does seem like it could
be a regression.
