Dear Maintainer,
On booting the packaged 6.19.8 and 6.19.11 Debian amd64 kernels on my desktop, there is a hang during early boot in the initramfs as systemd-udevd enumerates devices. This ends up timing out after ~100 seconds, and the system never comes up properly (though there might be another aspect to that, as device-mapper fails to map a number of LVM volumes, I am investigating that issue separately). systemd-udevd ends up in unkillable sleep, something also evidenced by kernel messages indicating that the udev-worker task remains blocked. It appears the issue originates from the amdgpu driver (also evidenced in the kernel task blocked messages).
I checked, and the issue is present in the upstream Linux kernel as well. I was able to use git bisect to pinpoint the commit from which the issue is exhibited (between 6.18.0-rc2 and 6.18.0-rc3):
