You shouldn't fsck write-enabled file systems.  The usual things I run=20
whenever I'm in single user mode are (the order *IS* important):

 =09# adjkerntz -i
 =09# swapon -a
 =09# fsck -p
 =09# mount -u /
 =09# mount -va

Probably because you have already remounted your root file system as=20
read-write.
