Hi, I've just come across the exact same bug on my x86_64 machines, but 
unfortunately I won't have the time to start bisecting this before 
tonight or tomorrow morning.

In any case, the culprit must be one of these patches:

https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git/diff/queue-6.15?id=9cc80b684b4f77d6c54fc0f1d34ecfe559838702&id2=f724d2960e671efa0e5bcb51327690f791923e4b

I had built a 6.15.2 kernel with the patch queue from tree id 
f724d2960e671efa0e5bcb51327690f791923e4b a few days ago and that kernel 
works flawlessly.

Today, I built a kernel with the patch queue from tree id 
9cc80b684b4f77d6c54fc0f1d34ecfe559838702 and that kernel crashes when 
trying to boot on x86_64 with the same error messages that Ronald 
reported yesterday.
