I have a similar problem, however my system fails to boot and periodically prints PCIe BUS Error messages. I'm currently using Fedora 28 with 4.16.12-300.fc28.x86_64 which allows me to start the system correctly. If I try to use a kernel version above that (e.g. 4.16.16) then the system hangs at boot printing out messages like: PCIe Bus Error: severity=Corrected, type=Data Link Layer, id=00e0(Transmitter ID) device [8086:a118] error status/mask=00001000/00002000 [12] Replay Timer Timeout How reproducible: At each boot This is the output from dmesg ...

*********** 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 28 kernel bugs. Fedora 28 has now been rebased to 4.17.7-200.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 experience different issues, please open a new bug report for those.
No more ACPI BIOS Error (bug) message with 4.17.7-200.fc28 kernel thanks
