Description

After the update from DragonFly 4.6 to 4.8 my (not so recent) desktop
system (AMD Phenom(tm) II X6 1045T Processor / Sapphire RadeonHD 6450
FleX / two screens) became unstable. After about 20min to 1hour I got

a) a sudden reboot
b) random pixel (noise) on the whole screen
c) the screen kept blank after idle/powersafe

In the case of (b) and (c) I could in most cases access the system
over the network (ssh) and kill the X server, with about a two to one
chance that the X server was restarted and useable or a complete
lockup.

Since the update to DragonFly 4.9 I get sudden reboots on any attempt
to start the X server (without xorg.conf) or when I execute "kldload
radeonkms".

With driver "vesa" in /etc/X11/xorg.conf the system is useable (apart
from the ugly resolution).

What is also strange (probably already since 4.8, but I am not sure)
are bad rendering errors. When moving the mouse cursor (moused) on any
of the virtual consoles, part of the mouse cursor and the character
under the cursor get rendered in three to seven or more previous
cursor positions.
