lcokdep self test failures

Hello,

I noticed that some of the lockdep self tests are failing on my device. The system is based on an NXP T2080 SoC, which has four 64-bit Power PC e6500 cores (2 threads each). 

See attached log.

I'm running kernel 5.12.6 straight from kernel dot org. No modifications.

For what it's worth, I have been experiencing random instability issues, which is what prompted me to enable lock debugging in the first place.

Thanks,
- Jake
