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

[Tim Darby]

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.

Any ideas on why it's doing that?
