[System] System freeze (amdgpu - flip_done timed out)

[boospy33]

For some time now (starting with Kubuntu 24.04 LTS), there has been a bug that causes the graphical interface to freeze when using AMD GPUs. Error in the journal:

amdgpu 0000:03:00.0: [drm] ERROR [CRTC:364:crtc-0] flip_done timed out

The behavior varies depending on the GPU type. Some systems freeze daily, some only while gaming, and others even during normal office work.
There is this post that, in my opinion, describes this issue very well:

https://forum.manjaro.org/t/system-f...el-6-12/176608

I'm using an “AMD Radeon RX 7900 XTX” here. Fortunately, it's only happened maybe once or twice a month. Mostly while gaming, but also a few times while working, which was really annoying.
After such an incident, a reboot is necessary. ACPI stops responding. A reboot via SSH is possible, but depending on the severity of the issue, it can take a little longer.

According to the post above, the bug has now actually been fixed starting with the following kernel versions (hoply):

6.18.44, 7.1.8, and 7.2-rc7

I don't know if the bug will be fixed (backported) in Kubuntu 26.04.1, but as a workaround, I installed the Liquorix kernel: https://liquorix.net
The kernel is always up to date. So far, the issue hasn't occurred again. But since it happened quite rarely here, I'm not 100% sure.

Anyway, I just wanted to share this info with you guys in case any of you are also affected by this bug.

Many greetings

Thanks, yes that sounds the right one.

The more folks that add themselves to the bug report, the more likely action might be taken; I assume it is something that can be backported.

I myself prefer Xanmod over Lyquorix, as the latter has added some instability for my hardware a bit more often than I'd like, while Xanmod has had much fewer issues (for me).

I hadn't heard of that at all, thanks for the hint.

Of course, ymmv.
