https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D261198 --- Comment #7 from Mark Johnston <markj@FreeBSD.org> --- Hmm, I wonder if we can avoid stopping the callout when td->td_lock !=3D sc->sc_lock. In that case, the thread is in the process of going to sleep = and will abort in sleepq_switch() anyway. I don't think sleepq_switch() can sa= fely abort the callout, but I believe it should be ok to leave it be. That'd be= a rare case, and see the comment above the problematic callout_stop() call. --=20 You are receiving this mail because: You are the assignee for the bug.=
