Segfault on Arch Linux / AMDGPU

[valters-tomsons]

Version: e4c9c292e57d39136df2d46d1e9b66eba53f3bd3

OS: Arch Linux (5.14.14) GPU: Radeon RX 590 Mesa: 21.2.4

Tried running with sudo and using setcap with no results.

VAAPI

Log: here Backtrace: here

When VAAPI drivers are installed, it crashes right after starting sunshine.

Software (x264)

Using software encoder, it crashes while trying to create a session.

Log: here Backtrace:

Additionally, lldb seems to print:

I actually didn't start getting this issue until AFTER I configured the KMS portion, which I initially skipped, but nothing could connect, so I went back and did the KMS step, and then it gives me the segfault

[Melechtna]

Interesting news, I DON'T get the issue, when I use the git version from the AUR. MIGHT be because you need to compile against newer kernels.

Further findings. If you perform the setcap, it just breaks entirely even with the git. But other than an audio issue, it functions correctly in Arch Linux as of now.
