Hello developers, We are trying to validate a Software file based encryption with standard key by disabling Inline encryption and we are observing the adb session is hung. We are not able to access the same filesystem at that moment. Please note, we don't see any issues on validating the standard key with Inline encryption HW. Test: adb push/pull of 1MB file with a sleep of 1s between each push & pull on the encrypted filesystem for 10 iterations and device going to hung at 7th iterations.
