Very interesting. I have a Supermicro X11SSH-TF with Xeon E3-1275v6, and when I try to upgrade from 6.10.3 (which is rock solid) to 6.11.5 it locks up hard almost immediately as well, if it even makes it through boot. I've had issues where the system locks up hard when I try to use the iGPU to transcode, so I've stopped doing that until some magic version appears where it works, but the system is stable with 6.10.3 otherwise. I may have to try disabling it in BIOS as well. Not ideal. but may be the only way to run 6.11.x+ unless someone sorts it out.

I'm having a similar issue with QuickSync locking the system up hard. This is on a Supermicro X11SSH-TF with E3-1275v6, 16GB of memory. I've had it happen with Plex, Handbrake, and, lately, I've been using Tdarr, all of which can trigger the issue seemingly at random. I thought it might be a thermal issue, but after putting a giant CPU cooler on, it hasn't seemed to resolve the issue. Doesn't look like anything gets written to syslog, so I've had to do a hard boot via IPMI. Would love to be resolve this so I can use transcoding consistently. It can work for relatively long periods, or fail a couple of files in. Is 16GB not enough memory maybe?

I'm using an E3-1275v6 with P630 in a Handbrake docker doing QuickSync-based h.265 conversions and it seems to be working fine. I had been using it for Plex as well but there was something that would happen where the box would lock up randomly when using both so I disabled it for Plex for now. May have been a thermal issue, and I've upgraded cooling since as well. Not sure if that helps, but it's another data point.
