>Environment:
  3.0-980320-SNAP's GENERIC kernel with the following /etc/fstab.

% cat /etc/fstab
/dev/sd0s1b     none                    swap    sw 0 0
/dev/sd1s1b     none                    swap    sw 0 0

/dev/ccd1c      /var/mail               ufs     rw 1 3
/dev/ccd2c      /home                   ufs     rw 1 2
/dev/ccd3c      /data                   ufs     rw 1 2
/dev/ccd4c      /var/spool/news         ufs     rw 1 3
proc            /proc                   procfs  rw 0 0

>Description:
  I use 5 ccd drives.
  As GENERIC kernel was compiled to utilize up to 4 ccd drives,
to attempt to mount /dev/ccd0c, /dev/ccd1c, /dev/ccd2c, /dev/ccd3c
and /dev/ccd4c will cause page fault. I want to not stop by page
fault although ccd drive can't access because too many drives.
  After making customized kernel with 'pseudo-device ccd 5' option,
it runs good.
