JC, thanks for the bug report. Since this is an ACPI issue, some additional information will be necessary to diagnose the problem. Can you please attach the output of the following commands?
uname -a sudo lspci -vv sudo lspci -vvn sudo dmidecode Please be sure to run these with sudo, they require root privileges; also please be sure to attach the output, there will be too much to handle in-line. When this happens, it would also be useful if you could attach /var/log/kern.log.0 after you reboot: This logfile will tell us what was happening when the machine died. Thanks! ** Changed in: acpi (Ubuntu) Status: Unconfirmed => Needs Info -- [Edgy] hibernate shuts down the computer https://launchpad.net/bugs/68619 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
