I started having this problem this weekend after I installed 13.04 (previously I was on 12.04, which was fine). Apparantly random filesystem corruption leading to unusable disk. It was happening pretty much every boot, taking 10 - 90 minutes before it went crazy. Adding ""libata.force=noncq" to my grub config does seem to have fixed the problem. Let me know if I can help solve this with any logs or anything.
