This isn't necessarily related to Resolve, but I know many of you use the Decklink/UltraStudio products and I've seen many of you discuss kernel panics. With that in mind, I'm cross-posting here...

I recently installed a new UltraStudio HD Mini in my workflow (with an Apple TB3 cable) and am being plagued by kernel panics.

Here is my setup:
iMac Pro
10-Core Intel Xeon W, 3GHz
64GB RAM
Radeon Pro Vega 64 w/ 16GB
OS: I've tried Catalina, Big Sur and Ventura, all with the same negative results

I am using Renewed Vision's PVP software (v3.5) to send key/fill out of the UltraStudio and into my ATEM. This actually works very well, however after some time the iMac begins to crash (it hangs for a minute or two, then reboots with the kernel panic screen). Once that starts happening, it typically crashes every 5min. After a few days I try again (after changing PVP and macOS versions) and it works fine for a few hours, then it starts consistently crashing again.

If I remove the UltraStudio, then the crashes stop, which leads me to believe this is a BMD problem.

I've tried both Desktop Video 12.4 and 12.4.2.

Like I said, when it's not crashing my computer, the key/fill I'm getting into my ATEM works wonderful.

Any suggestions from anyone running a similar setup? Or, if anyone is able to decipher Apple crash logs, I can provide that as well.

thanks
