Greetings!!
IBM CI has reported a kernel crash while running
selftests/powerpc/signal on a POWER9 pSeries system.
I attempted to reproduce this issue manually, but was not successful so far.
Below are the details of the crash as reported by CI.
Crash Details:

I’m now able to reproduce this issue reliably and consistently. The
reproduction steps are simple:
Run selftests/powerpc/signal

This issue is still present in 7.3-rc2 as well. Please let me know, if it’s invalid bug, I will make appropriate changes to my CI set up.
This is blocking for me.
