--- Comment #40 from Stefano Cherchi <stefano.cher...@wasabipeas.it> ---
I think the title of the page is misleading. We're experiencing the issue with
Red Hat 6.4, kernel version 2.6.32, on several Dell Poweredge r620 with
Sandybridge family processors (various models).

No notification with Red Hat 5, kernel version 2.6.18, on the same hardware.

So, as far as I can see, the bug has been introduced somewhere between the two
versions above. 

Some additional info:

The servers come from Dell with the power management policy set to "Performance
Per Watt Optimized (DAPC)" by default. 

We managed to "fix" the kernel notifications issue by setting the BIOS to
"Performance" instead. 

If you don't mind power consumption it is a quick way to get rid of the
problem.
