That patch cannot be applied alone. It would break the timekeeping in not so obvious ways as there will be unexpected sources of the NTP tracking error. IIRC, at least the following changes would need to be included with it. There may be others.

My suggestion for a fix would be to increase the limit in the failing test.
Thanks, that's what I expected. But I still wonder why the test is failing almost 100% of time for me on qemu-arm64 (running on x86). Is this a regression in 4.14, that was working at some point or was it never tested on arm?
