I'm using an MSI B350 PC MATE motherboard.
Machine: Device: desktop Mobo: Micro-Star model: B350 PC MATE (MS-7A34) v: 2.0 serial: N/A
UEFI: American Megatrends v: A.60 date: 07/27/2017
The problem still exists on F27.
I have also a MSI B350 PC MATE with UEFI A.70 from 09/20/2017, the cpu is a Ryzen 1600X.
I tried different kernel versions, last stable was 4.14.8-300.fc27.x86_64
now I'm on 4.15-rc6 and the issue still persists.

We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. The kernel moves very fast so bugs may get fixed as part of a kernel update. Due to this, we are doing a mass bug update across all of the Fedora 26 kernel bugs.
Fedora 26 has now been rebased to 4.15.4-200.fc26. 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 27, and are still experiencing this issue, please change the version to Fedora 27.
If you experience different issues, please open a new bug report for those.
Exactly the same message is still logged in Fedora 28:
Linux nyx 4.15.4-300.fc27.x86_64 #1 SMP Mon Feb 19 23:31:15 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
The last time I see this message in my logs is on 2018-04-21. So it seems to be solved. I guess that this is related to a kernel or bios update.

Thanks for letting us know.
