            Bug ID: 225036
           Summary: [kern] system does not reboot after panic, hangs
           Product: Base System
           Version: CURRENT
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: knz@thaumogen.net

Overview:

upon a kernel panic, the kernel prints the stack trace and the text "Uptime:
..." but does not proceed to reboot.

This is a regression since sometime in early December 2017.

Steps to reproduce:

- set up software watchdog, let watchdog timeout expire, or
- sysctl -w kern.kdb.panic=3D1

Actual results:

- text "panic: ..."
- stack trace
- text "Uptime: ..."
- no text printed on console after that

Expected result:

- text "Uptime: ..."
- subsystem shutdown
- text "Reboot ..."
- actual reboot

Build info:

FreeBSD kenax 12.0-CURRENT FreeBSD 12.0-CURRENT #3 r327725 amd64

kernel configuration:

include GENERIC
ident KENAX
options         KDB_UNATTENDED
options         SW_WATCHDOG
nooptions       INVARIANTS
nooptions       INVARIANT_SUPPORT
nooptions       WITNESS
nooptions       WITNESS_SKIPSPIN
nooptions       BUF_TRACKING
nooptions       DEADLKRES
nooptions       FULL_BUF_TRACKING

Issue did not occur on at least r323185, and possibly later kernels in early
december.
