Comment 67 for bug 585765

Fresh install of 10.04, seeing lock ups every couple of days, seemingly random. This system has been running 8.04 with no issues. On a couple of occasions while displaying video from firefox, also overnight when screen has been locked. Mouse + keyboard locked, screen showing purple Ubuntu boot screen, Flashing LEDs on keyboard and no response to 'ping'. After pressing 'reset' button on box the system fails to clean reboot and needs a power off/on to get a clean reboot. I have disabled all power management without any change. As above, I turned off visual effects early on but made no difference.
I also have a laptop which has never had this problem. Is there any info I can provide from these systems to assist with this issue.
