life takes place on the ibm (sd0)
there is a bad block on sd1 which pops up regularly,
but the drive is only used for news articles:

>Description:
i upgraded a 2.1.0-RELEASE to 2.2-960323-SNAP. rebuilt
the kernel with some unneeded drivers removed and with the
ccd-960325 driver added. i did not use the ccd driver yet.
after a day the machine crashed:
Fatal Trap 12: page fault while in kernel mode
fault virtual address: 0xc
fault code: supervisor write, page not present
instruction pointer: 0x8:0xf01b3921
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 = 3455 (sh)
interrupt mask = net tty bio
panic: page fault
panic: unknown/reserved trap
[same message as above repeated once more]
[system hangs here, no reboot]
shouldn't it reboot after the panic? at lease it says so in subr_prf.c.
>How-To-Repeat:
i hope it won't ;-)
