Hi Sam, thanks for the report. Is there any activity that you can do in order to trigger the crashes, or are them of nowhere? Also, what do you consider a crash - the machine reboots? Can you see something in the screen?
I'd like to see a kernel log when that crash happens - one alternative is to enable kdump, are you willing to do that? If so, please run: sudo apt-get update sudo apt-get install linux-crashdump (and stick with the defaults during installation questions). After that, reboot the system and execute "kdump-config show" and check if it mentions "ready to kdump". If so, when next time you have a crash event and machine reboots, please check if you have a file created in /var/crash/<timestap, in form of YYYYMMDD> and submit such files to us.
