Hi Danilo, I did a small comparison using only the data from my own report, specifically these two attachments:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2164910/+attachment/5994909/+files/kernel- freeze-2026-08-24.log https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2164910/+attachment/5994912/+files/linux- amdgpu-freeze.apport I also compared them with the clean AMDGPU initialization from the reboot immediately after the hard freeze. What stands out in my case is that the last relevant kernel messages before the system stops are: amdgpu: [gfxhub0] retry page fault followed by VM_L2_PROTECTION_FAULT_STATUS:0x00341051 for a GPU context belonging to firefox-bin. After that, there are no further kernel messages indicating a GPU reset, job timeout, EDID failure, or any visible recovery attempt before the hard reboot. On the following boot, the same kernel initializes AMDGPU and Display Core normally again. My current interpretation is therefore that this report points more strongly toward the GFXHUB / GPUVM / UTCL2 path than toward a clear display-resume / EDID failure. I do see broader similarities with #2142389 in the sense that both involve AMDGPU, kernel regressions, and hard display/system failures on AMD hardware. However, based on the data currently available in my own logs, I do not think there is enough evidence yet to claim that both reports share the same root cause. So for now I would treat this only as a potentially related data point rather than trying to place #2164910 directly into the same regression class as #2142389. If you find matching traces in your logs or in other reports, that would of course make the relationship much more interesting. Thanks again for taking a look. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2164910 Title: Ubuntu 24.04 freezes completely with amdgpu VM_L2_PROTECTION_FAULT on kernel 6.8.0-138-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2164910/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
