     lockdep: Introduce wait-type checks
Can you please avoid enabling

CONFIG_PROVE_RAW_LOCK_NESTING=y
for now?

As the changelog states, there are known issues and that's why the
config is default=n.

Hi Thomas,

Thanks for the advice, we have disabled CONFIG_PROVE_RAW_LOCK_NESTING.

Best Regards,
Rong Chen
