dmesg

Regression detected in kernel version v3.18-rc1.

Behaviour: Blank screen appears during boot. Normally KMS starts at this
moment, but since commit 1dce6264045cd23e9c07574ed0bb31c7dce9354f
("drm/nv50/kms: Set VBLANK time in modeset script") said behaviour
occurs.

dmesg log is attached, although it is overrun with messages like
[   23.119549] nouveau E[   PDISP][0000:01:00.0]     0x0840: 0x00000000 ->
0xc0000000

Bug #85160 has a patch attached that fixed the issue for at least one user.
Please test and report there if modesetting remains broken.
