Hi, I am seeing below crash in 11.2 FreeBSD kernel. The same was working fine earlier. It's getting continuous reboot.

Can you describe the system and software you are running here? The symbol found in the stack trace "t17proc" does not exist in the FreeBSD source tree.
ohk. It was running in C5 aws instance. Some of the C5 instance was running fine. But all of sudden started crashing on reboot. Since then all new C5 instance started crashing.
^Triage: fill out Summary and assign.
But I mean t17proc does not exist in FreeBSD, so this appears to be some derivative or modified OS?
Please attach a verbose boot log to this PR.
