Dump-capture kernel not executed for NMI kernel panic

[bmh8x]

Hi all,

When using ECI 3.0.1 Debian 11 (Bullseye) distribution, the dump-capture kernel not executed for NMI kernel panic by WDT(watch-dog timer) timeout, and I cannot get the kernel dump file.

On the other hand, kernel dump work with the orther non-IRQ kernel panic (ex: kernel panic occurred when writting to /proc/sysrq-trigger), and I can get the kernel dump file.

I am using Intel ECI 3.0.1 Debian 11 distribution(kernel version: 5.10.140-rt73-intel-ese-standard-lts-rt+) , and I think this is the same as the bug in the following report( This bug is fixed in kernel v6.1 )

Please provide me some information on how to fix the kernel dump function for IRQ-triggered kernel panic in ECI 3.0.1

Hi @bmh8x 

Yes, I saw the patch is only available in kernel v6.1

https://github.com/intel/linux-intel-lts/commit/05c6257433b7212f07a7e53479a8ab038fc1666a

Can you manually patch the file in kernel 5.10 and see whether it's work?
