I had a Ryzen 5 2600 CPU until today, when I replaced it with a Ryzen 9 5900X.
Windows doesn’t seem to have any problems at all (I dual boot) but KDE Neon runs into some problem while booting and reboots immediately.
I can’t see what the problem might be as it’s gone too fast, often before my monitor has time to change resolution (partway through booting).
If I add “nomodeset” to the kernel’s options, the system boots, but of course I’m not using the graphics drivers.
Since it seems to be relevant (unless it’s some other drivers that nomodeset removes), my graphics card is a Radeon RX 6800.
I’m on the latest kernel I can find in the repositories, 6.5.0-14-generic. As far as I can see, the CPU is supported since the 5.x series.
Incidentally, the Live version of KDE Neon (from a USB) doesn’t boot without nomodeset either.
What could the problem be? Is there a way to figure out what problem the kernel runs into on a normal boot?
#check boot logs and messages for issues
journalctl -b -p3
systemctl --failed
inxi -Fazu
sudo dmesg -tdH
Thanks. Here is the output of each of those. I didn’t notice anything very obvious, but I’m not sure how much of that is warnings that would appear anyway.

UNIT LOAD ACTIVE SUB DESCRIPTION

i’m just a bystander reading the tea leaves but maybe there’s something wrong with CPU and or it doesn’t work with your onboard audio chip?
it’s possible that windows can limp along without core 19 but linux is being more picky?
those hardware errors are a problem.
I’m not entirely sure those are related. I found this thread: System auto-rebooted... mce: [Hardware Error] in dmesg related to CPU - #9 by Daniel-I - Support - Manjaro Linux Forum which is about a different model, but I tried that setting in the BIOS and those “hardware error” messages have disappeared from journalctl, every time I’ve looked at it since.
However the problem continues. One time it did boot, somehow, but I restarted it immediately to see if it would happen again, and it went back to not booting.
well you cleaned up 3 errors… just keep going i guess
this is what the output of journalctl -b -p3 looks like on my machine
Dec 14 12:32:52 FXPC kernel: hid-generic 0003:1532:026C.0004: No inputs registered, leaving
that’s it, just one line… which has to do with my razer keyboard and there doesn’t seem to be anything i can do about it… it’s certainly not stopping me from booting.
perhaps you need a firmware update… either your bios or the microcode (or both)
in discover, you can check under settings to see if the sources are showing linux firmware updates are turned on, just in case that matters, and then check your mothboard maker to see if there is a bios update for newer CPUs
Those errors are back, despite that change, and I’ve no idea what to look at really.
BIOS is updated, done that days ago, and no newer microcode is available. I re-installed the package anyway, no change.
I wonder if I should try to just put back the old CPU, assuming I haven’t broken it. It’s just too much of a hassle, compared to any other component.
maybe.
or maybe just try re-seating the CPU in the socket once before you give up.
ur sure this CPU is fully supported by your old motherboard?
I usually trust pcpartpicker for that sort of thing, and it says yes.
see post #15
https://bbs.archlinux.org/viewtopic.php?id=266210
or
try sudo less -f /dev/mcelog and see what it shows (if anything).
Absolutely nothing in mcelog.
I think I’ll try to replace the old CPU later today.
I put the old one back and everything seems OK thus far…
If it was an overheating issue, hopefully I did better with the paste this time around. But I’m not experimenting more any time soon.
