(btw, does anyone here know if a Linux kernel can reboot automatically
after a crash? Nobody on the linux-lists I have found can answer...
Anyway, back to FBSD:)
If I enter config-mode at boot (kernel -c), the machine crashes when
trying to save and exit.
Fatal trap 12: page fault while in kernel mode.
Fault virtual address = 0x4
Fault code = supervisor read, page not present
Instruction pointer = 0x8:0xc020028e
Stack pointer = 0x10:0xc02e0ecc
Frame pointer = 0x10:0xc02e0eec
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 = Idle
Interrupt mask = net tty bio cam
kernel: type 12 trap, code = 0
Stopped at +xc020028e: movl 0x4(%eax),%edx

Oh, if I enable isdnd, the machine crashes on incoming calls, but let's
fix this first...
