SOLVED: Intel A310 Transcoding on RHEL - Broken?

[sgt.ogre]

Hello All,

I recently bought an Arc A310 to pass into a RHEL 10 VM (Almalinux specifically) and i get errors when transcoding files. Here is some general information. I think it is something with the guc and huc drivers. There is a failure in the huc logs:

• Jellyfin is running as a rootless container under an unprivileged user. I have added this user to the Render and Video groups
  
• Jellyfin can write to the config directory and it can direct play and use CPU transcoding on my test files just fine.
  
• I have tried switching between the VA-API and QSV encoders with no luck.
  
• I have attempted to turn on and off the lower power encoders, but i read that ARC uses them by default
  
• I have downloaded the linux-firmware and added it to the host
  
• I have modified the 2 mei settings mentioned here - https://gitlab.freedesktop.org/drm/i915/...ssues/7732
  

Here are some logs from the host machine:
