Does this look familiar to anyone? Any idea what might be causing
this? FWIW, I cannot reproduce it locally, so it's likely
environmental, but at this point, I don't really know where to begin
to look.
What HZ setting are the kernels on the problem host running with ?
IIRC we had someone else report a problem with this test suite on a
kernel built with HZ=100, rather than the more common HZ=1000
Ah, indeed they are running with HZ=100.
So this is a known problem? Is there a known fix?
Can you see if this makes any difference
