Subject: (XEN) Platform timer appears to have unexpectedly wrapped 10 or more times.
Date: Wed, 4 Jan 2012 18:23:43 +0100	[thread overview]
Message-ID: <20120104172343.GA30630@entuzijast.net> (raw)

Hi,

Sometimes, seemingly randomly, long-running Xen domains, using clocksource
xen, have their clock shift by ~3000 or ~36000 seconds, often with the dom0
complaining about clocksource tsc. 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.

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?
