  I'd check your HW - memory, power supply, ... Obviously something got
wrong.

  I'd say it is a faulty HW, not a software bug.

  I would first try to identify faulty HW (run memtest from a rescue CD
for example). When HW gets fixed, I'd copy the filesystem with 'dd' to a
different disk as a backup. Then run e2fsck to fix /dev/hda2.
