I have never seen the test fail on Debian/Ubuntu aarch64. So use Ubuntu! (joke)
It is difficult to investigate the issue with no access to the machine...
Can you reproduce the issue with ruby master? Can you try another Fedora+aarch64 environment? Can you measure how long the following command takes on the machine? (It takes less than one second on my machine, so I guess extending timeout would not solve the issue.)
make test-all TESTS="test/ruby/test_thread.rb -v -n test_signal_at_join"

I love Debian. :) It's my pleasure when I spend time with people in Debian community.

Yeah, it makes sense.

Yes, I will try to reproduce the issue on the better way to inform you later, after my current focusing tasks.
I reviewed every recent RubyCI arm/aarch64 failure, and this test did not fail in any of them. So failures must be rare. I'm going to close this. If this is still an issue and someone can come up with a reproducible test case, that would be appreciated.
