NMI received for an unknown reason error on BL460c G6 RHEL 5.4

I am seeing the following error message in the messages file and in dmesg:

Uhhuh. NMI received for unknown reason a0.
You probably have a hardware problem with your RAM chips
Dazed and confused, but trying to continue


After a reboot it is almost at the bottom of both dmesg and messages. It occurs in the same place every time I reboot the server.

Is this really a RAM error? I don't see any errors in the iLO or OA for the blade in question. The errors started showing up after HP replaced the motherboard in the blade this week.

Do you have the hp-health driver RPM installed?
It should intercept the HP-hardware-specific NMIs and interpret them correctly. You can download it from http://www.hp.com/go/support by searching for downloadables using your server model (BL460c G6) and then selecting your OS version (RHEL 5).

In generic PC hardware, a RAM problem is the most common reason for NMIs. But name-brand servers (like HP Proliants) will often use NMI for more than just RAM problem reports.

Hi Matti. What is the name of the driver? I have installed a bunch of stuff from the PSP.

One further note. If I put the blade in a different slot in the C7000 enclosure the error goes away. If I put it back in the original slot the error comes back.
