There isn't enough information here to debug it. Let me explain your log snippet so you can understand it.
* DCN 3.1.4 means hardware version (All PHX/HWK SoC have this version) * Display core (DC) means software version. It matches current Linux display promotion version. I guess the regression you point out is upgrading from: https://launchpad.net/ubuntu/+source/linux-firmware/20240318.git3b128b60-0ubuntu2.27 to https://launchpad.net/ubuntu/+source/linux-firmware-amd-graphics/20240318.git3b128b60-0ubuntu3.1 Using https://gitlab.com/kernel-firmware/linux- firmware/-/blob/main/contrib/get_amdgpu_fw_version.py You can see the versions of lib/firmware/amdgpu/dcn_3_1_4_dmcub.bin.zst 20240318.git3b128b60-0ubuntu2.26 (which should be same as 2.27 since no changes to that file) had: 0x8005300 20240318.git3b128b60-0ubuntu3.1 had: 0x8004800 Upstream has: 0x8006200 To me it looks like 20240318.git3b128b60-0ubuntu3.1 accidentally downgraded version. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2168847 Title: HWK SoC fails to boot with HWE 7.0 + linux-firmware 0ubuntu3.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware-amd-graphics/+bug/2168847/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
