I'd love to have more info - I actually looked at your original report,
and it's one of those "impossible" things as far as I can tell. The low
bit of the work "pending" flag should acts as a lock on workqueues, and
serialize access to one workqueue totally - so having it show up with a
pending timer is "strange" to say the least. The only two ways to clear
the "pending" timer is by running the work-queue - either for the timer to
have gone off (for the delayed case) _or_ the timer not to have evern been
set in the first place (for the immediate case).

So more information would be wonderful.
