Hey sorry for the delay. I found the real issue and I was previously wrong the kernel regression didn't fix the issue. It just happened to work for a few times in a row and fake me out. I once again had chatGPT put together a quick write up, I hope it helps.
Although in my own words what happened was I kept getting a AMDGPU error like noted above. I didn't notice at first notice it was failing to load the "integrated graphics" (Granite Ridge [1002:13c0]) that doesn't exists on my 9600x. I blacklisted it in grub and after several successful reboots the issue seems to actually be fixed. My PC seems to also boot MUCH faster. Here is the info organized by chatGPT for me and some logs I used to find the issue in the zip file. ### Summary Kernel falsely detects a non-existent GPU on Ryzen 9000 (Granite Ridge) CPUs, causing amdgpu firmware load failures and boot instability. --- ### Update — Identified Root Cause This issue is caused by the kernel incorrectly detecting a non-existent integrated GPU on Ryzen 9000 series CPUs. System specs: - CPU: AMD Ryzen 5 9600X (no iGPU) - GPU: Radeon RX 9060 XT [1002:7590] - Kernel versions tested: 6.14.0-32, 6.14.0-33, and 6.14.0-34 (bug present on all) The kernels enumerate an additional phantom GPU: 0e:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Granite Ridge [Radeon Graphics] [1002:13c0] Because of this, the amdgpu driver attempts to load firmware for that device and fails repeatedly: - "failed to load ucode" - "Fatal error during GPU init" - "probe with driver amdgpu failed with error -110" This causes slow boots or complete lockups during startup. --- ### Workaround Add the following to `/etc/default/grub` and run `sudo update-grub`:GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.ids=1002:7590" After reboot, the system boots normally with no errors and no phantom GPU. --- ### Notes The bug affects all tested kernels and appears related to how Granite Ridge CPUs expose a placeholder VGA device with ID `1002:13c0`. Please ensure the amdgpu driver ignores this phantom device on Ryzen 9000 (Granite Ridge) CPUs that lack integrated graphics. ** Attachment added: "logs showing found error" https://bugs.launchpad.net/ubuntu/+source/linux-hwe-6.14/+bug/2126854/+attachment/5916865/+files/logs.zip -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2126854 Title: AMDGPU firmware load timeout and system freeze on kernel 6.14.0-33 (RX 9060 XT, RDNA3) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-6.14/+bug/2126854/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
