Fedora does not boot after upgrade to kernel 6.15.3 with amdgpu drm error

Ask Fedora

After I run sudo dnf upgrade -y which installed kernel-0:6.15.3-200.fc42.x86_64 my system is not longer booting unless during boot I choose the previous kernel 6.14.9-300.fc42.x86_64.

The log from failed boot has the following entry:

cze 24 12:48:05 demon kernel: amdgpu 0000:0a:00.0: [drm] *ERROR* dc_dmub_srv_log_diagnostic_data: DMCUB error - collecting diagnostic data

During the upgrade the following two packages were updated (in total 688 packages were altered) which might be of interest here:

Upgrade  amd-gpu-firmware-0:20250613-1.fc42.noarch               External User   updates
Upgrade  amd-ucode-firmware-0:20250613-1.fc42.noarch             External User   updates
(…)
Replaced amd-gpu-firmware-0:20250509-1.fc42.noarch               External User   @System
Replaced amd-ucode-firmware-0:20250509-1.fc42.noarch             External User   @System

I have AMD Ryzen 5 7600 CPU with integrated gpu.

Has anyone experienced something like this?

Arch Linux: [SOLVED] amdgpu framework [drm] dc_dmub_srv_log_diagnostic_data

Which amd gpu do you have?

7

Yes, I had the same problem and downgrading those two packages fixed it.

8

#metoo. Did you solve it? By downgrading these two libraries perhaps (as suggested by @Masoud)?

9

For the record my GPU is an integrated AMD Radeon Raphael.

10

In the meantime I’ve set installonly_limit in /etc/dnf/dnf.conf to 10, so the further updates won’t delete the working 6.14.* kernel

11

It’s not a kernel problem. It even breaks 6.14 if you upgrade those two.

12

Mine is an integrated one as well (Ryzen 9 9900X)

13

Yeah, probably Raphael then.

14

I beg to differ. Probably :slight_smile:
I have these installed with 6.14. kernel and it works

Installed packages
amd-gpu-firmware.noarch   20250613-1.fc42 <unknown>
amd-ucode-firmware.noarch 20250613-1.fc42 <unknown>

Or am I missing something?

I might be making a mistake then. I couldn’t get past Luks prompt last night with 6.14 and these two upgraded.
I need to figure out which one it is to report it back.

FYI: dnf will never remove the kernel you are running on.
You can set the kernel to boot from by default using sudo grubby.

Find the index of the kernel

sudo grubby --info=ALL

Set the default to that index

sudo grubby --set-default-index=X

Beware that a limit of 10 may mean that you fill up your /boot and cause issues becuase of running out of free space.

Just checked, it’s Granite Ridge [Radeon Graphics] (according to cpu-x)

18

Awesome. I reverted the limit back to default and set default to the last working one.

Great, thanks for checking. Will include this on my report back.

I’ve also update BIOS - AGESA to ComboAM5 1.2.0.3e Patch A (fresh and latest available for my mobo) but it doesn’t make a difference.

I have AMD Ryzen 5 7600 CPU with integrated gpu:

$ kinfo
Operating System: Fedora Linux 42
KDE Plasma Version: 6.4.0
KDE Frameworks Version: 6.15.0
Qt Version: 6.9.1
Kernel Version: 6.14.9-300.fc42.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 12 × AMD Ryzen 5 7600 6-Core Processor
Memory: 16 GiB of RAM (14.8 GiB usable)
Graphics Processor: AMD Radeon Graphics

#metoo after the update and I cannot even boot on 6.14.x.
Tried the solution from Arch forum, didn’t work either.
Any suggestions before I spend my day re-installing everything? :frowning:

Did you try downgrading those libraries?
