@superm1 you are right. There are same amdgpu error message when booting 6.17.0-3, I just did not notice them.
I looked for previous boot logs in /var/log, where they always used to be... Another thing broken by systemd, oh well... anyway, here's the problem, as far as I can see now, when I have the boot log: I have an automount unit for a network (nfs) share. And now, with the new kernel, kdump-tools, for some reason, trigger it, and wait for the mount to complete. But at this point, dhcp (NetworkManager?) is not running yet, so mount stalls. And kdump-tools stalls. And there is no (obvious) way to activate text console, and we are stuck. So the difference that the new kernel brought is that with the new kernel, kdump-tools (probably them, who else) try to `stat` /import, which cannot be mounted yet.
