and the test kernel in the above comment and I see the same behavior. No call
trace, but on both the test ends:

Hi,
Patch is now upstream,
https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git/commit/?h=next=7ccc4fe5ff9e3a134e863beed0dba18a5e511659

Hi Anju ,
The above test kernel add issue while setting up, so rebuilt the
upstream kernel with the patches mentioned above.
=> Perf fuzzer works fine and issue is not seen.
=> Thread IMC also works fine.

Verified with test kernel : Issue is resolved.
