https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D260393 --- Comment #92 from Dobri Dobrev <ddobrev85@gmail.com> --- (In reply to Michael Tuexen from comment #91) I hadn't had a chance to update to the latest stable/13. Just got a crash after 112 days uptime on stable/13-n248590-b7da472979a Here's what kgdb shows: Reading symbols from /boot/kernel/kernel...
