EDIT: Oops, don't know why I originally said 12.10. This is 12.04.

This is a work laptop and I didn't really use it over the Christmas break (22nd to Jan 1st). However, I have had three complete system crashes (Jan 3rd, 4th and 7th) since coming back. The complete system crash is everything will become unresponsive. No mouse/keyboard input. I have a system monitor indicator that will stop updating on screen. Can't move to a terminal session with Ctrl+Alt+F1, 2, 3, 4, 5 or 6. Not responding to pings or ssh connections. Lastly, it is a System76 Serval Professional 7. Two light indicators on the laptop will just be flashing (caps lock and I believe screen lock lights).

In addition, I can't find anything in logs related to it and the syslog has actually not updated anything since December 18th 9:17. That seems problematic that syslog has no updates have occurred since then.

Lastly, I did have some Ubuntu package updates right around that time:

Let me know if I can supply anything else. Thanks.

generally hard freezes like this are hardware related or in this case something related to your kernel upgrade. see the linux-image-generic (, line of your log.

also the lack of logs is very odd indeed. what does df -h say for your / partition. also if you do not have logs check

dmesg | less

how about dmesg anything there related to syslog. – strings Jan 7 '13 at 22:41
Did a search for syslog in dmesg and nothing. I installed experimental nvidia drivers back in November for the Steam Client. I have set it back to a non-experimental driver and haven't had a crash yet. Not really proof that fixed it, though. – Craig Jan 9 '13 at 17:26
could be driver related, still concerned about lack of logs, is that resolved? – strings Jan 9 '13 at 18:02
