Unable to access performance counters

I think I am experiencing the same as the author of this post.

rasmus@jetsonxaviernx1-desktop:/$ sudo dmesg | grep pmu
[ 1.195229] hw perfevents: failed to parse interrupt-affinity[6] for arm-pmu
[ 1.195272] hw perfevents: /arm-pmu: failed to register PMU devices!
[ 1.195315] armv8-pmu: probe of arm-pmu failed with error -22

They were told to get support via NVBug. I don’t know if or how I can access the answer.
Thanks in advance for your help!
