I learned that the clock kernel parameter is deprecated, it is now called clocksource. Still it is somehow gets ignored, and the kernel uses acpi_pm instead.

$ dmesg|grep clock Kernel command line: root=/dev/sda1 resume=/dev/sda2 rootdelay=1 ro vga=787 clocksource=pit Measured 18368 cycles TSC warp between CPUs, turning off TSC clock. Switching to clocksource acpi_pm

Look at this: $ cd /sys/devices/system/clocksource $ ls -F clocksource0/ $ cd clocksource0/ $ ls -F available_clocksource current_clocksource $ cat available_clocksource tsc hpet acpi_pm $ cat current_clocksource hpet Playing around here might help or give ideas. As far as I know, 'tsc' is a bad choice for a clocksource (not sure why or if I am even correct), but a good fallback when acpi_pm fails and hpet is unavailable. Under KVM, I have a special KVM clocksource which synchronizes with the host clock. Similarly on Xen.

Oh, thanks. It seems I only have acpi_pm. Is that normal?

$ cat available_clocksource acpi_pm $ cat current_clocksource acpi_pm

I removed openntpd completely and disabled time sync. The vm still freezes eventually. Also, I cannot set clocksource to anything else than acpi_pm

Let's go back to brainstorming mode, i welcome any new ideas.

OK, Let's start over. I haven't a clue about your clocksource loop, but I would suggest rebuilding virtualbox using: http://aur.archlinux.org/packages.php?ID=9753 Of all the different packages, I have had great luck with this one. Just download the tarball and untar/ungzip with: tar -xzf virtualbox_bin.tar.gz cd virtualbox_bin/ makepkg -s sudo pacman -U virtualbox_bin-3.2.10-2-x86_64.pkg.tar.xz Then test again. -- David C.

That might help but if it where me I would build it using "A clean chroot"

The instructions to do that is here:

 http://wiki.archlinux.org/index.php/DeveloperWiki:Building_in_a_Clean_Chroot

That way you would not get anything you didn't bargain for ;)

Another suggestion would be to download the puel version from Oracle/Sun (http://download.virtualbox.org/virtualbox/vboxdownload.html) and install it. I use it on two boxes and have not experienced any problems. Myra -- Life's fun when your sick and psychotic!

That's what the AUR package virtualbox_bin is doing.

Sorry bout that, I should have read the pkgbuild first. -- Life's fun when your sick and psychotic!
