I'm getting a kernel panic on one of my machines. It's reproducable, occurs on every shutdown. I've swapped out hardware, but the problem doesn't go away. Fatal trap 12: page fault while in kernel mode fault virtual address = 0x1c fault code = supervisor write, page not present instruction pointer = 0x8:0xc04b51e3 stack pointer = 0x10:0xd52fa780 frame pointer = 0x10:0xd52fa78c code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 297 (syslogd) trap number = 12 panic: page fault Uptime: 3m43s Dumping 512 MB Note sure if it's relevant, but the user space process in qustion is always syslogd. One interesting note, if I try to shutdown during the background fsck_ufs, no panic occurs but 'Syncing disks' never completes (just keeps writing numbers). Below is a backtrace. And in case it's needed my kernel config is attached. For what it's worth this looks similar to this panic: http://lists.freebsd.org/pipermail/freebsd-current/2004-October/041354.html Thanks in advance for any ideas...
