eagle lake dp dmesg
HP Compaq 8000 E7500 displayport shows timeout errors in log, and doesn't come
up at all. Monitor is IBM ThinkVision, connected with straight cable. VGA
works.
Default Ubuntu kernel and DRM-Tip show same symptoms: monitor shortly coming
out of power save, then going back and no picture.
BIOS screen shows up through DP well enough.
DRM-Tip dmesg with drm.debug=0xe attached.</pre>
