I do not know if the below will suggest any test cases or not. I just
note it for superficial similarity and possibly more usual hardware
than the old PowerMac context that I have.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=230451 "nanosleep hangs forever"
seems to be an example on an old ~500 MHz 586-class AMD CPU when
kern.timecounter.hardware was ACPI-fast instead of TSC.

The 2018-08-08 report was for 11.2-Stable.
