            Bug ID: 90979
           Summary: [IVB] KMS blackscreen but responsive keyboard at boot
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Intel

Kernel log

Occurs with the latest versions of Arch (linux 4.0.5, linux 3.19.3), Ubuntu,
Debian (linux 3.16) (all built today). Dualbooting with Windows 8, which starts
up fine.

Samsung NP680Z5E-X01FR
Intel Core i5 3230M
Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Venus XT [Radeon HD
8870M / R9 M270X]

Booting without any kernel options results in a blank screen, but I can log
into the console blind, run commands, reboot.

The blank screen actually comes after some dmesg log text (past udev and some
more). Adding MODULES="intel_agp i915" to the kernel causes the screen to go
blank much earlier.

Disabling KMS makes some things work but is not satisfactory. I am stuck with a
800x600 resolution on a 1366x768 screen (though under some circumstances I have
found it corrected), and am kinda missing out on the available graphics
hardware.

Turning off ACPI allows me to see the login prompt but then the keyboard is not
responsive anymore.

Excerpts of the kernel log

This line pops up between the second and third call trace:

[drm:ironlake_crtc_disable [i915]] *ERROR* failed to disable transcoder A
