thank you all for your help!
If you have not already done so, you can drop into runlevel 1, login as root, and then run "jfs_fsck /dev/sda4" and see if that reports (and fixes) any problems.
I had similar very funky behavior with an xfs filesystem that had been corrupted due to memory problems. I had to repair the file system to make the funkiness go away.
