Subject: CPU MTRRs and linux kernel

Hi everybody,
Abour rhis warnning in boot log:

WARNING: BIOS bug: CPU MTRRs don't cover all of memory, losing 61952MB of RAM

 
I
 searched a lot however didn't find a clear solution. Does AMD new 
processors (62XX) have problems with new kernels or old kernels??
Mine is:

Linux n1 2.6.32-24-server #39-Ubuntu SMP Wed Jul 28 06:21:40 UTC 2010 x86_64 GNU/Linux

Should I upgrade?
