Hello,
i'm experiencing periodic kernel panics on a server with FreeBSD
7.0-STABLE #0: Tue May 20 19:09:43 CEST 2008.
My big problem is that the system is not performing memory dumping
and/or automatic reoboot,
it just stays there.
Here' console output:
em0: watchdog timeout -- resetting
kernel trap 12 with interrupts disabled
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic_id = 00
fault virtual address = 0x14
fault code = supervisor read, page not present
intruction pointerr = 0x20:0xc056e2ce
stack pointer = 0x28:0xe537fc08
frame pointer = 0x28:0xe537fc28
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = resume, IOPL = 0
current process = 29 (em0 taskq)
trap number = 12
panic: page fault
cpuid = 0
It just stays there, unresponsive (no automatic reboot).
Any ideas?
Thanks,
Daniel

But, there is also the question of why you are in the watchdog path in the first place. Jack
