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. --=20 You are receiving this mail because: You are the assignee for the bug.=
