Heh. Have I mentioned how much I *hate* those kernel threads being frozen?

Just for fun, could you try if the patch that just rips out the freezer
calls from the STR code just fixes the problem too (instead of reverting
that commit?)

It was done by Matthew Garrett <mjg59@srcf.ucam.org>, and you should be
able to find it in the kernel archives under the subject

Re: pcmcia resume 60 second hang. Re: [patch 00/69] -stable review
Message-ID: <20070527184402.GA21161@srcf.ucam.org>

and it would be interesting to hear if that just solves the problem for
you too.

There's a different (but related to all the same freezer problems) patch
by Rafael Wysocki <rjw@sisk.pl>:

Re: [RFC][PATCH][EXPERIMENTAL] Make kernel threads nonfreezable by default
Message-Id: <200705291415.31970.rjw@sisk.pl>

which would also be worth trying out.
