Hi I have the same problem with 4 machines (hp dl385, AMD), the problem appears one time per machine and per month ... No chance to re-produce it faster. On some other machine with another AMD processor, I never had this problem. Olivier Hanesse reported the problem on some Intel CPU and not on other processor. I'm using debian squeeze, with xen-hypervisor-4.0-amd64 4.0.1-4 linux-image-2.6.32-5-xen-amd64 2.6.32-38 (dom0) that last changes that I have done is to add cpuidle=0 to hypervisor command line. stable since 3-4 weeks (...) I have e test system that runs 20 paravirt. domus, with wheezy, with same problematic HW, with xen-hypervisor-4.1-amd64 4.1.2-2 linux-image-3.1.0-1-amd64 3.1.6-1 (dom0) and this system never had the TSC jump problem. but test system are test system .... I would be happy if you could reproduce the problem faster a me, so testing new xen / dom0 version could be easier ... thanks and regards Philippe > -----Original Message----- > From: xen-devel-bounces@xxxxxxxxxxxxxxxxxxx [mailto:xen-devel- > bounces@xxxxxxxxxxxxxxxxxxx] On Behalf Of Josip Rodin > Sent: Wednesday, January 04, 2012 6:24 PM > To: xen-devel@xxxxxxxxxxxxxxxxxxx > Subject: [Xen-devel] (XEN) Platform timer appears to have unexpectedly > wrapped 10 or more times. > > 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.
