The number changes if the hypervisor is explicitly told to use clocksource=pit, but it still happens. It doesn't seem to be particularly hardware-specific. See also http://bugs.debian.org/599161 I see from the archives that others have reported this problem here in February last year, but I couldn't find a resolution. Can anyone help?
