Hi James,

Sorry for the delay in replying to you. Do you think it could be some
patch from d51b1b33c51d147b757f042b4d336603b699f362 or
23d1dea55520c5cf89849279cd25de4da8392687 ?

I was able to reproduce it using the CKI kernel from d51b1b33, but not
from commit 2fce7ea0.

We don't have a kernel build for 23d1dea5, but if you want I can try
it next week.

Also, it seems I can only reproduce it on kernel build that adds some
debug flags when we build with selftests enabled.

kernel build: https://s3.us-east-1.amazonaws.com/arr-cki-prod-datawarehouse-public/datawarehouse-public/2022/03/23/499569088/build_x86_64_redhat:2242251830/kernel-mainline.kernel.org-x86_64-d51b1b33c51d147b757f042b4d336603b699f362.tar.gz
kernel config: https://s3.us-east-1.amazonaws.com/arr-cki-prod-datawarehouse-public/datawarehouse-public/2022/03/23/499569088/build_x86_64_redhat:2242251830/kernel-mainline.kernel.org-x86_64-d51b1b33c51d147b757f042b4d336603b699f362.config
