It seems as if the blackmagic linux kernel driver somehow locks up?

I'm using debian sid with Linux kernel 5.19.6 and desktopvideo 12.4.

Has anyone experienced this before? Any ideas? If further information should be required, please ask!

I've encountered similar issues on Linux systems with all the BMD devices I have to test with (UltraStudio Recorder 3G, UltraStudio Monitor 3G, UltraStudio HD Mini, and a range of DeckLink cards in Thunderbolt enclosures).

The common thread between the systems with problems is that the computers have Thunderbolt 4 ports. The exact same devices work perfectly fine on other computers ruining the same OS version and same Desktopvideo version, just these computers have Thunderbolt 3 instead.
