I tried the procedure on DebuggingKernelSuspendHibernateResume. After I typed "sudo pm-suspend" the system was suspended (I thought the "no_console_suspend" boot option would prevent the actual suspend but produce useful information). Anyway, after suspend the computer would not wake up so I had to do a restart.
I also tried the procedure on DebuggingKernelSuspend. You can't execute "sync; echo 1 > /sys/power/pm_trace; pm-suspend" using sudo, you have to log on as root. The only way I know to do that is to reboot in recovery mode and log on as root there. The system was suspended there but did wake up when I pressed the power button. I may be relevant that this computer also had boot problems. There's usually a pause during boot of 10, 20 seconds before the Ubuntu logo is displayed and boot continues. Sometimes the system hangs but power off/on helps, but on a few occassions, the system just will not boot. Booting into recovery mode would show that booting halted after a message "Clocksource tsc unstable". Booting with the option "clocksource=acpi_pm" will get the system to boot and then it will boot normally (for a while I guess). ** Attachment added: "dmesg.txt" http://launchpadlibrarian.net/38303607/dmesg.txt -- [Packard Bell BV EasyNote MZ35] - Computer freezes when resuming after a suspend https://bugs.launchpad.net/bugs/399831 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
