[DragonFlyBSD - Bug #2635] Stablize drm/radeon KMS drivers for new xorg

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #2635 has been updated by yellowrabbit2010.


Horray! With commits 7d32ff5365a2d04afa460e716477566727967980 and f6201ebf294c18bfb1c3d199bed847ab481b3099
my Radeon 6670 becomes alive! Great job.

Now I can use new xorg with kms driver. 2 monitors work nicely --- mplayer plays video on the big one, when I can do something simple on the little one.

But I cannot do something like "make -j 3 buildworld" --- after 5--25 minutes computer will restart.
Without dumps. Few strings remain in /var/log/messages:
