--- Comment #3 from Alan Somers <asom...@freebsd.org> ---
I can trigger this panic pretty reliably on 12.2 by doing a firmware update of
an mps card. Updating a Broadcom 9207-8e card from firmware 19.00.00.00 to
20.00.07.00 succeeds, but when resetting the card it hits this panic. I
haven't yet tried to do the update on 13.0, nor have I tried updating from
20.00.07.00 to the same version, 20.00.07.00. The stack trace is a little bit
different:
panic: camq_remove: Attempt to remove out-of-bounds index -2 from queue

time = 1617145521
