dmesg log

When adding radeon.mst=1 to kernel parameters all of my displays get killed.
The distribution I am using is Void GNU/Linux

Is there a particular reason you filed this against the Xorg driver instead of the kernel driver? If you really think there's a Xorg driver issue, we'd need to see the Xorg log file and maybe also the xrandr output.

No it kills all displays right after the kernel is loaded and xorg isn't started so I know it's related to that. I'm new to bugzilla. Should I have reported this to bugzilla.kernel.org instead?

No, we prefer this bugzilla for kernel driver issues as well. Reassigning.

The radeon driver does not support MST.
