Here (with AMD Thames [Radeon HD 7550M/7570M/7650M],
<https://bsd-hardware.info/?probe=64c92d49d9#pci:1002-6841-103c-17a9>), the
radeonkms module loads without difficulty. 


My first observation of the crash of Xorg was with SDDM (the norm for me), 

% sysrc sddm_enable
sddm_enable: YES
% 


With SDDM _not_ started automatically, I can trigger the crash as root with 
startx, 

# grep -v \#\  /root/.xinitrc
#!/bin/sh
/usr/local/bin/twm &
sleep 1
exec xterm
#
