Description mat dida 2023-08-02 17:23:54 UTC 
My system: OpenSuse Leap 15.5,  "out of the box" installation (no particular configuration, tweaks or 3rd party driver). My GPU AMD Radeon 7600. It worked fine until last kernel-firmware update.

After the last kernel-firmware update (packages: kernel-firmware-all-20230724-150500.3.3.1.noarch.rpm and all the other kernel-firmware-…) there was a major problem with the graphical interface: a message (just for a second between grub menu and kde splash screen) complaining about "amdgpu… something", I could login and see the desktop but then the GUI freeze in a matter of seconds.
On reboot I tried “safe mode…” from grub menu, but I saw the same messages as before and the GUI frozen. 
Next I have reinstalled the system with all the updates except the last kernel-firmware and this way the system works properly.
Unfortunately I didn’t keep any log of the error.


How to Reproduce: boot a x86-64 system with a GPU AMD radeon 7600 and the last kernel-firmware update(version 20230724-150500.3.3.1).

Could you test with the kernel in OBS Kernel:SLE15-SP5 repo?
  http://download.opensuse.org/repositories/Kernel:/SLE15-SP5/pool/
Test with and without the latest kernel-firmware update.

If this kernel also doesn't work with the latest firmware, please boot with "firmware_class.dyndbg=+p" boot option, and get the dmesg output.  If you can't get it after the boot, reboot with "nomodeset" boot option (to disable the native graphics), and extract the previous kernel boot log.  You can downgrade to the older kernel-firmware packages there to recover, too.

Yesterday I saw a new kernel update available (5.14.21-150500.55.12-default).

I installed it, but keeping the old firmware and it worked.

Then I updated the kernel-firmware packages to the last version (20230724-150500.3.3.1) and it worked.

Therefore, referring to the original title, it was not a bug in the firmware package but probably some kind of incompatibility between the prevoius kenerel(5.14.21-150500.55.7-default) and the latest firmware(20230724-150500.3.3.1).

Now with all the update in place the system works correctly.
I will change the title.
Thanks.

OK, thanks for the information.
Then it's basically fixed with the full updates.  Let's close the bug now.
