If so, we may be hitting what I was afraid of, since the second pipe appears to be off: --- i915 disabled +++ i915 enabled - DSPBCNTR: 0x00000000 (disabled) - DSPBBASE: 0x00000000 - DSPBSTRIDE: 0x00000000 (0) - DSPBSURF: 0x00000000 - DSPBTILEOFF: 0x00000000 (0, 0) + DSPBCNTR: 0xd8004400 (enabled) + DSPBBASE: 0xffff6680 + DSPBSTRIDE: 0x00002c00 (176) + DSPBSURF: 0x0a02e000 + DSPBTILEOFF: 0x00000020 (32, 0) i.e. when we load i915, it tries to use pipe b to light up the screen, but it doesn't work. Even the HDMI is disabled: - HDMIC: 0x0000001c (disabled pipe A 8bpc SDVO DVI audio disabled +vsync +hsync detected) + HDMIC: 0xc000001c (enabled pipe C 8bpc SDVO DVI audio disabled +vsync +hsync detected) So this may be a case of 'not our bug', or at least not solely, since it means we need the switchable graphics handling support to work.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
