AMD GPUs are cursed for me

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Having a bleeding edge kernel can and will come back to bite you. There's a reason why many distros hold back with kernel updates for so long, there's issues that only can be found with user feedback.
From experience, "stable" in the kernel world doesn't mean much unfortunately. I encountered dozens of issues over various versions and different hardware already and it's the main reason I don't run rolling release distros on my main rig.
There's also been enough times where the latest Nvidia driver borked my test system at work so I'm fine with just not running the latest kernel instead.
I have the same problem with the LTS kernel. Just tried. First time it booted but locked up on shutdown. The next cold boot it immediately went to black screen after loading amdgpu. (
[drm:amdgpu_gfx_enable_kcq [amdgpu]] *ERROR* KCQ enable failed
). Next boot too. All with kernel 6.6.14.That's strange, 6.6.14 is the same version that's on Fedora currently. My friend with a 7900 XTX is still on 6.5.0 so I can't get him to test that version right now.
Fix is merged already though: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=9c2f0338bbd132a4b12b988004d796798609d297 Should hopefully not be long before it is backported.

Until then I might have to live with Windows or don't reboot too often. I have yet to figure out how long I need to keep this machine off the power for it to behave like a cold boot. 10s apparently didn't cut it in my latest try (it's a new PC so I still have to learn its quirks).
