Kernel panic - not syncing: An NMI occurred.

Hieu_Ho — Fri, 10 Mar 2023 05:58:26 GMT

Hi team,

I have a DL360g10 - ILO 5.

OS - Red Hat Enterprise Linux Server release 7.6 (Maipo) - 3.10.0-957.el7.x86_64

It shows this error. Any ideas?

I already check ILO log, system info, etc.

Application Watchdog NMI Detected - The Application Watchdog NMI has been signaled (per the system configuration policy).

Hi,

May be you need to log a support case with HPE or Red Hat. HPE document.

As a workaround, can you perform diagnosis?

Thank You!
I work with HPE but opinions expressed here are mine.
