Bug Description
-- CPU: Intel Core(TM) i3-2100 CPU @ 3.10GHz (Sandy Bridge)
-- GPU: Intel Corporation Sandy Bridge Integrated Graphics Controller
[8086:0102] (rev 09) (prog-if 00 [VGA controller])
-- system architecture: 32-bit
-- Linux distribution: Ubuntu 10.10 and 11.04
-- Package versions:
libdrm - 2.4.21-1ubuntu2 and 2.4.23-1ubuntu6
xf86-video-intel - 2:2.12.0-1ubuntu5.2 and 2:2.14.0-4ubuntu7
kernel - 2.6.35-
This system is a desktop one with a eDP->LVDS converter (CH7511B) for the
all-in-one panel and it only works with VESA. As soon as KMS kicks in it goes
black and doesn't come back. External monitors still work fine, its just the
internal panel that is black. Ubuntu maverick and natty were tested, as well as
a 2.6.39.1 kernel. the 2.6.39.1 kernel actually hung with an external monitor,
with additional messages like these at the end
PCH HDCP audio interrupt
Followed by a two additional DRM messages:
<7> [ 17.668935 ] [drm.ironlake_
<7> [ 245.874118] [drm:i915_
