Unfortunately I hastened to say that everything is working. With
latest drm driver my desktop constantly and randomly panics.
Sometimes FreeBSD panics at startup WM ( fluxbox or KDE4 - not matter,
panic with both ).

The most frequent hang when I run any application ( konsole, psi,
xterm, firefox ).

I can get backtrace - although i have swap (ZVOL-based, auto partition
from bsdinstall ) partition and dumpdev="AUTO:

% dumpon -l
ada0p3

FreeBSD does core file ( broken functionality ? ). So i can make
copy&paste, alll what can I do - share poor (sorry) quality images:

All panics related to locks. I hope some of FreeBSD developers looks on this.

But in general, drm-next-4.7 is unusable and very unstable for me.

Thanks!
