Hi all,
We recently upgrade from CentOS 5.8 to CentOS 5.9 on kernel-xen-2.6.18-348.3.1.el5, and after booting into the new kernel, noted large amounts of these messages every second or so in the logs:
Mar 30 21:38:35 atlas2 kernel: Warning Timer ISR/0: Time went backwards: delta=-1393683849 delta_cpu=22316151 shadow=225003685197135 off=129240997 processed=225005208029053 cpu_processed=225003792029053
On both the dom0 and the domUs.
Some reading indicates that this _was_ a fault fixed in 2009/2010, but it seems to have resurfaced on the latest kernel.
For now, we've reverted back to an earlier kernel.
Has anybody else seen this recently, or got any insight?
Thanks,
David

Hi. not enough about your configuration(dmsg, xm dmsg, hardware, etc). Maybe your system clock runs very fast and any service(for example ntp) goes backwards system time.
I have found several links about your question:
