/dev/dri missing after upgrade to 25.04.2.1

TrueNAS General

I was running TrueNAS Scale 25.04.1 without any issues. Today I upgraded to 25.04.2.1 and noticed a few of my applications are not working. All of them have GPU passthrough enabled. The logs tell me that /dev/dri is not available.

Iā€™m using an AMD Ryzen 7900X CPU. Any idea how to get /dev/dri back? Thanks

I managed to fix the issue. I had an Incus container set with GPU passthrough as well. Once I removed it from there and rebooted the server, /dev/dri was available again.
