Created attachment 1457540 [details] dmesg.txt Description of problem: Somewhere with the kernel 4.16.x, my Intel wireless card started to disconnect often. This most often happen when I pick up my laptop which was unusued for few minutes – long enough to blank screen. When the screen unblanks, wifi reconnects, there are errors in dmesg. Afterwards wifi is rather stable for few hours. This laptop never had such problems in few years I'm using it with Fedora. Version-Release number of selected component (if applicable): 4.17.0-200.fc28.x86_64 It has started with 4.16.x, but I waited hoping 4.17 will improve situation. It did not. How reproducible: Almost always. Steps to Reproduce: 1. 2. 3. Actual results: [474862.944035] iwlwifi 0000:03:00.0: Error sending REPLY_TXFIFO_FLUSH: time out after 2000ms.

We apologize for the inconvenience. There is 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 28 kernel bugs. Fedora 28 has now been rebased to 4.18.10-300.fc28. 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 have moved on to Fedora 29, and are still experiencing this issue, please change the version to Fedora 29. If you experience different issues, please open a new bug report for those.
This bug is being closed with INSUFFICIENT_DATA as there has not been a response in 2 weeks. If you are still experiencing this issue, please reopen and let us know if the bug is still present on the latest kernel. (Please note: sometimes bugs get mistakenly closed during our mass closing. If you think your bug was closed in error please reopen)
