Test case "general/time/leap-second/leap_hrtimer" is running out of time on aarch64 and ppc64le machines. At the very least I have seen this happen on 94z and 92z, but others could be affected as well.

The thing is that while x86_64 takes hour and a half to complete, those two architectures go on for more than 3 hours until stopped. The logs do not seem to show any specific error happening, so maybe they are just slow, or maybe the have something getting stuck.

Some examples of this happening:
