Then it takes couple of seconds and the error is reported. Unfortunately error message does not survive reboot so it is shown in attached picture only, taken from screen. Not deterministic problem, with following traits: - appears randomly but more than once every 10 shutdown at average - does not seem to be related to system up time. It was observed after few minutes of system uptime as well as after days of uptime - does not seem to be related to any particular activities / tasks system had been performing during uptime Misleading information is that system was going to reboot. That is not the case - system was going down for halt and turn off. When it occurs computer remains in that state, does not turn off, CPU utilization must be high (fan is spinning like a crazy). Any key stroke would initiate system reboot. Please let me know what (and how) further symptoms can be collected Regards Kris -- You are receiving this mail because: You are the assignee for the bug.
