Looking for solution.... CPU soft lockup detected for CentOS 5 and IBM BladeCentre

One of my IBM BladeCentre node hangs and the log messages generated
"BUG: soft lockup - CPU#1 stuck for 10s! [rpciod/1:3646]"

I have been looking around, but found a reference but not a solution though. I have seen other forum that 
RHEL 5.X CPU soft lockup detected in PAGE_LOCK_ANON_VMA - IBM BladeCenter and System x 

While running the Red Hat Enterprise Linux 5.x (RHEL5) family of products, the kernel may report the following error:
BUG: soft lockup - CPU#XX stuck for 10s!

Where XX can be the number of any processor in the system.
The associated stack backtrace points to page_lock_anon_vma as the code running at the time of the soft lockup detection.

Affected configurations
The system is configured with at least one of the following:
  • Red Hat Enterprise Linux 5, any update
This tip is not system specific.
This tip is not option specific.
Note: This does not imply that the network operating system will work under all combinations of hardware and software. Please see the compatibility page for more information:

This behavior will be corrected in subsequent families of Red Hat products. For more information, contact Red Hat at the following URL:
