--- Comment #43 from Christian Hartmann <cornogle at googlemail.com> ---
additional note: in all cases of KMS without a visible screen, the machine does
not reboot or shutdown ordinary. If its only black,  I always send an init 0|6
but I have to always use the powerbutton to really reset / reboot the machine.

With no KMS enabled, all is fine with reboots etc, also if the screen is
visible with KMS enabled.

Hope that helps too
