Meanwhile I was able to identify more by removing "quiet" from the grub loader. The pcc_cpufreq_init does not seem to hurt the booting - these are just warnings popping up.
The following messages appear on the console before the server freezes: [ OK ] Finished Load Kernel Module fuse. [ 62.887855] systemd[1]: Mounting FUSE Control File System...

After this, no further messages, no login prompt, server does not react to keyboard input anymore. Only a hardware reset works in this case. Out of ~10 server reboots this problem occurred 4 or 5 times. Could it have something to do with drm? I've seen a drm driver error during earlier boot phase.
