Well, I've been trying a couple of kernels, 6.1.0-17/11, and with both the system freezes sometime in the way explained below. I did a RAM test which was passed successfully, but I guess I should also make a GPU RAM test, something I really don't know how to do. For the usual RAM I used MEMTEST86+ as a live ISO.
Now I'm trying kernel subsubsub version 16 since a couple of days ago and the system has not frozen yet. But I'm not very optimistic. Anyway, how can I test GPU memory? Best regards.
