*********** 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 27 kernel bugs.

Fedora 27 has now been rebased to 4.17.7-100.fc27.  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 28, and are still experiencing this issue, please change the version to Fedora 28.

If you experience different issues, please open a new bug report for those.

This is on Fedora 30 with the 5.0.17 kernel. I think there is also a slight screen flicker whenever it happens, but I'm still working to confirm that.

Comment 7 VonChair 2019-10-24 06:30:58 UTC

Can anyone impacted by this issue post the current SATA storage controller make, model, and driver version if available in use by an impacted system?

Comment 8 Cristian Ciupitu 2019-10-24 07:33:27 UTC

The motherboard is Intel DZ77BH-55K (coupled with an Intel i7-3770 CPU).
