Package power limit notifications & Core power limit notifications
 
Hi guys. I just loaded my first 6.3 RHEL server, and I noticed every time i go to the console, there are a TON of Package power limit notifications & Core power limit notifications up on the screen.
Does that mean I have power problems with this new server?

Could be a known bug https://bugzilla.kernel.org/show_bug.cgi?id=36182. As per there, you may be able to tweak BIOS settings (or not ..).
Check the type of chip you have.

anon091 12-12-2012 06:35 PM
Thanks Chris, I'm going to add to the bug to see if i can help them solve it, I bet i'm in the same boat as these guys.

chrism01 12-12-2012 06:56 PM
Good luck.
(not sure if this should be moved to Hardware ?)

anon091 12-14-2012 05:39 AM
Thanks. I'm not sure either where this really belongs at this point haha.
