In case this matters, after the first try of 7.0.4+deb14-amd64 (which made the machine freeze), I tried the 6.7.12-amd64 kernel again (this is the other kernel I keep and often use as this was the latest one where Debian bug 1072063 was absent), and for the first time, I also got a kernel Oops (this is not due to a recent upgrade as the last rebuild of initrd.img-6.7.12-amd64 was on 2025-12-13):
