Hi,

I'm currently investigating our problems right now in our HP server (DL360-G4p) and we have RHEL 5.2 linux installed on it.

Then, I found error messages in the linux messages log files.

The message are the following:

kernel: Uhhuh. NMI received for unknown reason 21 on CPU 0.
kernel: Do you have a strange power saving mode enabled?
kernel: Dazed and confused, but trying to continue
kernel: Uhhuh. NMI received for unknown reason 34 on CPU 0.
kernel: Do you have a strange power saving mode enabled?
kernel: Dazed and confused, but trying to continue
hpasmd[4826]: CRITICAL: hpasmd: An Unrecoverable System Error (NMI) has occurred

kernel: Uhhuh. NMI received for unknown reason 24 on CPU 0.
kernel: Do you have a strange power saving mode enabled?
kernel: Dazed and confused, but trying to continue
In HPSIm i have :
An Unrecoverable System Error (NMI) has occurred

Thanks for your assistance

Shalom,

The message has been seen before on other platforms. Does not from the text of it seem very professional eh?

Based on the variety of OS it is seen with, I tend to think there is a hardware problem.

I recommend booting into hardware diagnostics and checking the CPU.

Hi,
Look at the knowledge base. For example the advisory

You could update your bios.

I have seen a similar error on my IBM/LINU serves . But all i recollect is sending DSA logs to IBM to check hardware errors..
