This article provides information on Linux - "Package Power limit" and "Core power limit" notifications.
Linux - Various distributions - It seems to affect systems with kernel 2.6.18 and above.
Intel based CPU
“Core power limit ” and “Package power limit ” notifications being continuously logged in the /var/log/messages.
/var/log/messages will show notifications similar to:
Jun 21 09:34:55 compute-0-15 kernel: CPU7: Core power limit notification (total events = 1)
Jun 21 09:34:55 compute-0-15 kernel: CPU21: Core power limit notification (total events = 1)
Jun 21 09:34:55 compute-0-15 kernel: CPU25: Package power limit notification (total events = 1)
Jun 21 09:34:55 compute-0-15 kernel: CPU3: Package power limit notification (total events = 1)
This issue is currently still being worked by some software vendors.
In the meantime, there are 2 possible workarounds:
Clear PLN flag adding clearcpuid=229 to grub.conf or;
Set the machine's Performance Profile to Max Performance in the BIOS, if that setting is available (Please, be aware that power consumption may increase if this option is chosen).
Power Limit Notification is a feature that was added to the Sandy Bridge processors from Intel. The notification does not indicate a problem, and should not be reported as a Critical-level message.
The occurrence of the power limit notification is routine, and the system should not be reporting the messages. They can be ignored.
