'sudo smartctl -l error /dev/sda' gave a list of errors. Latest error recorded was 12. http://pastebin.com/f32a37289 My other hard disk on /dev/sdb has ZERO errors. One pass in memtest gave ZERO errors in RAM. Ubuntu forums is having a down time right now(!?), but a gist of google results imply impending disk failure... Surprising thing is my machine works just fabulous when it is not acting up. On going through /var/log/messages, I found the following log before the various restarts: ++ Aug 5 09:10:51 mark2 kernel: [ 55.341694] Clocksource tsc unstable (delta = -236835484 ns) Aug 5 09:15:43 mark2 exiting on signal 15 ++ http://pastebin.com/f307b6625 On 5th August, between 8:30 to 10 AM and between 7:30 to 9:30 PM when the instability occurred, there was a bunch of these unstable messages. -- Rohit V.
