Bug 268451: x11-drivers/xf86-video-ati immediate core dump
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=268451



--- Description ---
After years of working perfectly (including, most recently, on
13.1-RELEASE-p2), xorg-server crashes immediately upon startup.

xorg-server 21.1.4_1,1
xf86-video-ati 19.1.0_6,1

There is no xorg.conf file involved.

The chip involved is reported by pciconf -lv as 
    vendor     = 'Advanced Micro Devices, Inc. [AMD/ATI]'
    device     = 'RS780L [Radeon 3000]'

The only thing I know of that changed was that I upgraded the following

it.  Any suggestions, requests for more information?  Thanks.
