--- Comment #1 from Mark Johnston <ma...@freebsd.org> ---
To fix this, I think it'd be sufficient to:
1. Use callout_init_rw() to initialize ipf_slow_ch, and remove the locking in
ipf_timer_func().
2. Use callout_stop() instead of callout_drain().
This assumes that the global ipf lock is not dropped while executing
ipf_timer_func(), which I believe is the case. If so, then callout_stop() can
cancel a pending callout without sleeping, avoiding the problem which triggers
that warning.
