It's likely that you have NO_OSNOISE_WORKLOAD set. The default value
is OSNOISE_WORKLOAD; rtla relies on it not being set, and rtla
timerlat -u resets it to the original value after it ends, so usually,
everything works. But it breaks either when you set
NO_OSNOISE_WORKLOAD manually or when rtla timerlat -u crashes (and
fails to set it back).

I just realized that the tests are not running rtla timerlat with -k
and upstream, it has been defaulting to user threads for a long time,
so that's probably not it.
