*********** MASS BUG UPDATE **************
We apologize for the inconvenience. There are a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 29 kernel bugs.
Fedora 29 has now been rebased to 4.20.5-200.fc29. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.
If you experience different issues, please open a new bug report for those.
i can confirm that starting w/ the 4.20 kernel series suspend/resume cycles are working again for xps 9575 systems provided that wireless networking is disabled before suspend action.
