In 4.17-rc1 I have weird problems with network manager... and I also have screensaver kicking just after resume. Searching the git logs: - The most interesting change is the consolidation of clock MONOTONIC and clock BOOTTIME. Clock MONOTONIC behaves now exactly like clock BOOTTIME and does not longer ignore the time spent in suspend. A new clock MONOTONIC_ACTIVE is provived which behaves like clock MONOTONIC in kernels before this change. This allows applications to programmatically check for the clock MONOTONIC behaviour. As discussed in the review thread, this has the potential of breaking user space and we might have to revert this. Knock on wood that we can avoid that exercise. =2E..I believe you are breaking userspace for me. How can we check that?
