Hi. Could you follow the instructions at https://help.ubuntu.com/community/DebuggingSystemCrash:
When the crash occurs, press Alt+SysRq+1 followed by Alt+SysRq+t. If using a text console, you should see a trace dumped to the screen. If the system is sufficiently alive, it will also be logged to /var/log/kern.log and visible in the output from dmesg. This information shows where the crash occurred, and should be included in any problem reports. If the output is not saved in any file, or the system is so bad off that you cannot retrieve it, you can either take a digital photo, or hand write the results. Almost all of the output is important (so please don't copy the one line you think is important, because context means everything). -- Ubuntu 6.10 Hangs at Restart https://launchpad.net/bugs/68772 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
