Hello. I have tested old kernels linux-image-5.17.0-2-amd64-unsigned (5.7.6-1) linux-image-5.17.0-3-amd64-unsigned (5.7.11-1) In first case - error is absent, in second - error is present. Also, I check the BIOS settings. There is no any MMIO settings. This is notebook, it have very small BIOS settings at all.
