On a vanilla installation of 9.1-RELEASE (straight from memstick), the system panics during a reboot when the ipmi kernel module is loaded. The system behaves normally when the ipmi kernel module is not loaded. Ordinary crash dumps didn't work, as the ability to write to the RAID on the system in question appeared to go away during the panic. However, I was able to get the system to save a crash dump to a USB drive. 'kgdb' output is below. I've also included the output of /var/run/dmesg.boot (also below). The panic only seems to occur during reboot. The system is otherwise stable, and has been subjected to some moderate disk- and memory-intensive loads for testing. The only reasons the panic at reboot bugs me are a) it causes at least some of the filesystems to be uncleanly unmounted, and b) it shouldn't happen. :-\ The hardware is a Dell PowerEdge R720, nothing terribly exotic. I don't think it should make a difference, but I disabled the "lifecycle controller" stuff in BIOS. Again, I've exercised the host; it seems to be OK. I looked the PR database over and didn't see any bugs similar to this one. I've also spent a bit of time with Google, and it looks like this is something not many people have yet encountered. I don't know if that's because GENERIC doesn't include ipmi.ko and so people generally aren't encountering it, if my hardware is strange, some combination of the two, or something else entirely. The crashdump compressed to about 26MB, which is a bit large to include here. Please let me know if having access to it will help, and I'll try to make it available. Also, let me know if you need additional information, or need me to try something else. Thanks in advance. ####################################### kgdb OUTPUT STARTS root@setup3:/boot/kernel # pwd /boot/kernel root@setup3:/boot/kernel # kgdb kernel /var/crash/vmcore.0 GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.

-Bump- Same issue here on FreeBSD 9.1-RELEASE-p9 #1: Mon Jan 6 00:03:33 PST = 2014, disabled ipmi and its back to working normally. I'm running on a = Supermicro X7SPA-HF motherboard. Daniel=
This was worked around by dropping the lock in the syncer in r272366, but that change was never MFC'd. I'm committing a more proper fix today as well.
Update actually. If you aren't running watchdogd then this was worked around post 9.1 release and should be fixed in newer releases already. *** This bug has been marked as a duplicate of bug 171524 ***
