The system runs fine, but has some problems when trying to reboot. The system panics when starting to mount the file systems. It then prints out some information about the panic, and proceeds to panic a 2nd time and reboot. This happens so fast I cannot read the information. After the system has panic'd the 2nd time, the system reboots and fscks the file systems at which point everything comes up ok. I wonder if/how something is being/not being written to disk which causes the system to panic, and is fixed via the fsck. This happenned about 6 times today out of 20 reboots. I have rebuilt the kernel with debug and will attempt to replicate the problem with the current snap on the machine, and with todays/tonights snap on a 2nd machine. If anyone has any ideas about what might be going on here, I'd appreciate any pointers. I've included some dmesg output below. Thanks! John Copyright (c) 1992-1999 The FreeBSD Project.
