Kernel Panic

Postby caesar305 » 2015-11-25 06:19

Hello,

Running Debian 7.4 on a HP DL380 Gen9, we are having random kernel panics, about every 15 days or so.
During the panic everything locks up and therefore does not write anything to disk (log messages, crash dumps, etc.). We were able to capture the screen using serial port redirection and this is what we found:

[1460183.180585] Kernel panic - not syncing: An NMI occurred, please see the Integrated Management Log for details.

I have seen some bug reports on ubuntu, not sure if they are related.

Ubuntu is not Debian, there would not be any relation ship, or shouldn't be,
Do you have ubuntu ppps or sources mixed in on your system ?
It would help to have more details,
Like, did you do some "updates" or upgrades, just before all of this started ?

Hello, no we have not done any updates. This was a clean install of 7.4. The only difference on this equipment vs other servers we have was we needed to compile the hp raid drivers manually and rebuild the initrd image, otherwise it would not boot. I am assuming this was because of the new HP hardware on this particular server. Other than that, they are setup exactly the same as our other servers.

The above may be the culprit, but how about checking if there is hardware error by memtest (memory check) and fsck (file system check)?
