The tests rt/test-cputimers{1..3} fails because of a kernel bug fixed
in:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v5.0-rc4&id=93ad0fc088c5b4631f796c995bdd27a082ef33a6
Not a "minor timing issue".
Thanks for pointing that out. It is fixed in the 4.20.6 kernel, but not in
the 4.20.1 kernel (which I was using).
I can't figure out which kernels are affected. If someone can figure that
out, I'll add it to the notes in the book on glibc test failures.
For 4.19, it was broken in 4.19.13 and fixed in 4.19.19.
The fix for division by zero (which caused this problem) was in the
4.20.0 release, and as you said, the fix is in 4.20.6.
But the fix is not in the 4.20.1 release. I looked at the code and it
isn't there.
