I have tried the additional kernel parameters intel_pstate=force and cpuidle.off=1 but unfortunately this didn't solve the problem. The freeze still happened at around 50% of the boots. I now wiped Bullseye and installed Buster. The very same server was rebooted at least 10 times without any hiccup/freeze/crash. Seems there are indeed some major issues which are not solved yet. If they come from Debian Installer, they may be related to bug #987441 ( https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=987441). Or if they are Kernel related (Buster uses 4.19, Bullseye 5.10) it might be a completely different problem.
