If your disk is dying this could mean about anything.
Try smartctl from smartmontools package. What does it report about the
health status of your disk (after some testing)?
Try e2fsck again to see, if it detects 'new' errors on your file system.
I hope you have good back ups. You could try diff -r against your backup
(mounted ro). However, if your disk is damaged and loads and runs
garbled kernel stuff, you risk hosing your backup. Therefore it might be
safer to investigate by booting a rescue system from CD or usb-disk. YMMV.
Take care, good luck,
Johannes
