Jerome Marchand requested to merge jeromemarchand/centos-stream-9:bz2035164 into main Jan 20, 2022

Bugzilla: http://bugzilla.redhat.com/2035164

There a bug in trace_percpu_buffer that can cause a kernel panic. The bug has been sitting there for a while, but was only revealed by the new osnoise tracer. It's easy reproducible on ppc64le.
