Description

I'm getting some strange behavior on my laptop. After a few hours my
mouse and keyboard start freezing up, and my keyboard will occassionally
produce a few extra chars. Lookking a dmesg, I get a lot of this:

devstat_end_transaction: HELP!! busy_count for root0 is < 0 (-1)!
devstat_end_transaction: HELP!! busy_count for root0 is < 0 (-1)!
devstat_end_transaction: HELP!! busy_count for root0 is < 0 (-1)!

Any ideas on why it's doing that?

I'm also seeing these "busy_count" errors on the machine I recently built
(DF 2.9.1.176, x86-64, SMP) that has root, swap, and data partitions
encrypted. These errors appeared right after I did a hammer mirror-copy and
they are happening during the daily scheduled hammer maintenance.
