New 4.17.6-100 on AMD Ryzen Processor

In Case anyone is interested, the new Fedora 27 - 4.17.6-100 is unstable at least on the AMD Ryzen processor. Don't know about any others.

From power on, it boots to the line "Started User Manager for UID 42" (repeated twice) and then ends with a dead mouse cursor and no GUI. Can't use <ctll-alt-f2> to get a command line. A hardware reset at this point allows a proper boot to the login screen. I've tried this several times and it is consistent.

Once it is running, a restart from Gnome will boot correctly.

Update your BIOS. Fedora 28 has many packages updated, e.g. you could benefit from newer mesa. Use those updated images to check if it behaves better. With hardware as new as those APUs, the newer software, the better.

Also, there's been lots of fixes for Raven Ridge in kernel 4.18, so you could give rawhide's kernel a try.

Since I wrote this there have been two updates pushed by Fedora. One of them resolved the boot problem that is the subject of this post and also resolved the "cut/paste to/from clipboard" problem that was driving me nuts!

Therefore, this subject is closed.

I've seen this issue previously. It looks to be an NVIDIA GPU issue. Take a look at a previous thread and its solution and try it out:

I would say file a bug report at Redhat Bugzilla and let them know your computer specs, etc. It should not be having this issue on 4.17 or F27.

Thanks. I've seen that thread befoe but the video here is whatever comes with the Ryzen processor - Fedora thinks it is radeon vega graphics. The graphics identify as "AMD Raven". I suspect this is a somewhat buggy chip as there are MANY errors reported during boot regarding the ata buss, missing UEFI data, etc. However, onece started, it does work correctly but rather slowly. I assume that the O/S has installed workarounds for these issues.

Interesting. Please report the bug on Bugzilla then.

Sure, happy to do that, but it is outside my experience. Can you please give the correct URL for Fedora Bugzilla?

Also, I see postings today for problems playing videos (MP4, I assume) on Fedora 28. Just to report it, using the Video option, I get the same result - desktop and keyboard die and audio continues. Needed a hard reboot to get out of it. Firefox playing MP4 works OK.

I tried the latest ( version of Fedore 27 and it is unstable too, but most of the problems can be bypassed. For the record, this version will not boot from a power-off reset much of the time, but sometimes it does. Usually it ends with a dead mouse cursor, no Gnome screen, and no keyboard. A hardware reset from the dead boot screen usually works (7 of 8 tries). From a Gnome reboot command it might, but then again it might not, seems sort of random. I still haven't figured out how to get KDE which I have been trying to do for a couple of months, can't test if it is Gnome.

Something that might be relevant: I went away for 1 hour, when I returned, machine had hundreds of copies of command line and Evolution open on the desktop to same location. Gnome background graphic had changed to a grey screen. Tried to kill command lines and after about 5 minutes of watching them die one at a time, I did a hardware reset to get back on.

top was showing Gnome using 1.2% of CPU and 6.8% of memory (4 Gb).
