You probably need to change the entry for your root partition in
"/etc/fstab".  2.2.6 now requires that this entry be explicit: e.g.  If
your installation is on the second ide hard disk ( slave drive on ide
channel 0) and on the first partition, change the line:

/dev/wd1a          /          ufs     rw          1     1

to:

/dev/wd1s1a          /          ufs     rw          1     1

                ^^

Notice that the partition or "slice" is now explicitly designated.
