Finally built a new rig, and wanted to ditch Windows.
Got KDE neon up and running, booted into it, got my browser mostly back to how I like it, ran an update for my video card. I didn't notice the screen blackout and come back like it normally would for a video update, but I don't think that has anything to do with my current issue. I tried to restart to make sure it was running, and the update part of discover showed up and said I had a couple hundred updates to get, no big surprise there, since it is a fresh install.
Then it hung on fetching updates, and while I could browse my list of programs, I couldn't do anything else. So I did a hard shut down and powered back up.
It sticks on some kennel warnings and won't go any further.
Obviously I can't really do anything from there that I know of.
I also can't even get it to boot with the install media. That just sticks on a black screen. I can tell the monitor is actually showing black, as it doesn't give the "NO SIGNAL" warning. I have no idea what to do from here since I can't get it to react to anything, much less know how to fix anything if I could get in.
As for what the warnings say, there are 6 or so lines saying the same thing: problem blacklisting hash (-13), and one more that says nvme2: failed to set APST feature (2)
I haven't put anything on nvme2 yet, I haven't even formatted it yet, just the primary drive (nvme0). So I'm not sure what could possibly be wrong with it yet.
It was an option, but I was planning on trying a couple different distros, and I know ext4 has better compatibility, and didn't want to format the whole drive back and forth, or have multiple systems at once time on different partitions. Once I settle permanently if it is an option I've heard some say it's better, but haven't looked into it yet.
Edit: just realized this sounds a little consider to the other comment.
What I mean to say is at least it was before I installed any programs and got to try it out. Based on another comment, I now know this is a rolling release which is not something I'm interested in anyway.
