... and this sounds like the perf tool expecting to single-step over
signal handlers, whereas (on arm64) we deliberately single-step into
them, so you can run into a loop for this case.
Could you please provide me more information? Do you think it is
a kernel bug and should be fixed? Or it is an invalid testcase for
aarch64?
Thank you.
