dmesg extracted from the tarball
Please remove any modeset=0 parameters, reboot, and grab the dmesg. If this leads to black screen, please try to ssh in or do it blind. Created attachment 125827 [details]
Dmesg without modeset=0
I've attached three files dmesg_ok.txt when everything runs ok.
dmesg_vblank_timeout.txt and Xorg.0.log when i get black screen but everything else works well so I can get these files through ssh.
