New logs with drm.debug=14

Took me about 5 suspend/resume actions to replicate it this time. Before doing
the 5'th suspend, I waited for DPMS to turn off my display, and then pressed
some keys to get my screen back to normal, then I suspended the system. So, I
think it might be related to DPMS somehow.

Like I said; upon resume, the screen blanking only happens in FULL-SCREEN
software, and it only seems to go away if I return the windows to their normal
size, using some key combo, or if I use my Dell's pointing stick.
