Check which clocksource your system is set to: sudo cat /sys/devices/system/clocksource/clocksource0/current_clocksource
Check which clocksources are available: sudo cat /sys/devices/system/clocksource/clocksource0/available_clocksource I get output like this: tsc hpet acpi_pm I'm betting your current clocksource is tsc, which the kernel seems to favor as default on some systems, but just doesn't keep track of time all that well. Append clocksource=acpi_pm or clocksource=hpet to your kernel options depending on what available_clocksource returns. If you have Grub2, you would edit the GRUB_CMDLINE_LINUX="" line in /etc/default/grub, then run sudo update-grub. For GRUB legacy, you can add clocksource=acpi_pm or clocksource=hpet to defoptions (for "normal" entries) or altoptions (for all entries) and then run sudo update-grub. GRUB will then append it to all of your future kernel entries. -- after upgrade to karmic with clocksource tsc drifts over 7.25 sec every 10 minutes https://bugs.launchpad.net/bugs/483316 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
