This server has been in service for a while and all of a sudden late last week it started spitting out these errors several times per second.

It is causing my system to run at 25% on all CPUs even if it is not doing anything.

Any ideas why this happens

Hi,

We are facing the same issue with our Dell R620 server on linux kernel 2.6.32-358.11.1.el6.x86_64.

Did anyone found solution to this issue?

Thanks

Rajesh

Feature added to Sandy Bridge CPUs, required kernel update to correct.

Another 'fix' reported in this link is to change Server Profile to 'Performance', which will avoid the speed stepping that is used to reduce power consumption during low utilization, which is causing these messages.
