Kernel panic - not syncing: An NMI occurred.

[Hieu_Ho]

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?
