# uname -sr
FreeBSD 11.0-RELEASE-p13

# sysctl kern.panic_reboot_wait_time
kern.panic_reboot_wait_time: -1

According to source code (sys/kern/kern_shutdown.c), FreeBSD should not reboot after a panic.
However it does, without displaying any message.
I also tried setting this sysctl to some seconds, same behavior.

I tried some debugging, kernel enter poweroff_wait(), but does not seem to enter shutdown_*(), where it should finally wait in shutdown_panic().

I would like my systems not to reboot after a panic, so that I can get the stack trace on the console if dump failed, thus allowing me to know what happened.

Thank you !
