There is a confirmed workaround for this issue.

By changing the clocksource of Dom0 from "xen" to "jiffies", the issue appears
to be eliminated.  After doing so, I was able to run burnin testing in dom0 and
three domU's for 72 hours without any errors.

This change is made by doing
echo "jiffies" >
/sys/devices/system/clocksource/clocksource0/current_clocksource

Note that although the error messages appeared from all of the clocksources on
the machine (clocksource/0, clocksource/1, etc), changing only the
current_clocksource for clocksource0 was enough to fix this.  The others were
unaltered.
