dmesg output of boot and 2x failing kmscube run at end - some lines with usb/hdd detection removed to cut down length

I filed this bug at gitlab so probably the wrong location ?

https://gitlab.freedesktop.org/mesa/kmscube/issues/1

from there:

---

kmscube 
kmscube -M rgba

both work

gst-play-1.0 sometestvideo.mkv works

Running

kmscube -V sometestvideo.mkv

is expected to work but fails.

tested today again and in journalctl I get

I just wanted to run some simple "known good" test programs that use KMS (and OpenGL) before running or testing more advanced stuff but it seems that I already hit a wall :)
