To see what platform timer is being used, look for a line 'Platform timer is ' in Xen's boot output. To change it, specify for example 'clocksource=hpet' as a Xen boot parameter. Could you also send a few of the 'went backwards' messages, so we can see how badly time is getting skewed. Perhaps we can work out where the issue arises from too -- it seems that a significant proprotion of those who have issues with these messages are seeing them on AMD boxes. I haven't confirmed the correlation though. -- Keir On 3/7/08 12:44, "Sandesh" wrote: > Hi all, > I am getting lots of Timer ISR/0: Timer went backwards error... > due to which my dom0 is crashing.
