Running Jaunty on a one-month-old System76 laptop (system model "daru3"). The system sometimes freezes when I'm not doing anything - the screen freezes and the computer doesn't react to keyboard or mouse input except force-shut-down with the power button. While it's frozen, the Caps Lock and Scroll Lock lights blink green.
A quick google search suggested that this might be a memory problem, but I ran memtest86+ and it passed.
What's going on? Is there anything I can do about this?
