This sounds familiar - like file system corruption.

A check should be forced anyway. Use "fsck -f" to do so.

The easiest way is to boot from optical media (CD or DVD #1)
or USB stick. It _may_ be possible to boot into single user
mode (use "boot -s" after reboot) where / is mounted r/o.
There is no way to unmount / while the system is running,
even in single user mode this is problematic, so a second
(live) system seems to be the safest way.
