Did you get the same amdgpu_dm_atomic_commit_tail => dc_commit_state =>
dc_stream_log NULL pointer dereference as reported here?

If yes, this is a kernel driver bug, xf86-video-amdgpu just triggers it / the
Xorg modesetting driver avoids it somehow.

If not, please file your own report at
https://bugs.freedesktop.org/enter_bug.cgi?product=xorg&component=Driver/AMDgpu
and attach the corresponding Xorg log file and output of dmesg.
