update to latest package cause xorg-server to crash.
Updating packages:
from 1.20.13-2 to 21.1.1-3
xf86-video-ati from 19.1.0-2 to 19.1.0.r9.g5eba0006e-1

Steps to reproduce:
Update the package, restart the xorg server, watch it crash.
Reverting to previous pacakges fix the crash.

It's not possible to tell which system causes the crash between xorg-server and the xf86 ati driver since packages are mutually depends.

Full Xorg log file is included.

Test the vesa driver to sort out the ati driver updates.
Feel free to rebuild the new ati driver against the old xserver and downgrade to confirm this.

Please also check for known upstream bugs:

It seems the bug has been reported back here:
with a PR pending:

I confirm the driver no longer crash witch this patch. It seems to fix problems with xrandr also.
