Dear All,
I am running RHEL 6.4 in a PowerEdge R910.
When I do:
# dmesg | grep -i clock
I am getting a lot of messages with this text:
"Clocksource tsc unstable (delta = 580433372 ns). Enable clocksource failover by adding clocksource_failover kernel parameter."
I have been looking for a solution. Concretely, Red Hat propose the following:

That is, changing the clocksource. However it did not solve the problem.
Actually, when I do:
cat /sys/devices/system/clocksource/clocksource0/available_clocksource
my options are: tsc jiffies
so when I change the clocksource to jiffies, the problem remains.
I must say that the kernel writes those messages when the server is powered on/rebooted. Then, after a few minutes it stops.
Have any of you had this problem? Did you find any solution? Is it a symptom for a hardware problem?
Many thanks in advance for your help.
Best regards,
Sebastian.
