dmesg - Ubuntu 14.10 with kernel 3.16.0-29-generic
If I connect display with HDMI connector, display shuts down. Dmesg shows the
following message:
[ 1.413309] WARNING: CPU: 0 PID: 118 at
/build/buildd/linux-3.16.0/drivers/gpu/drm/i915/intel_display.c:1426

[ 1.413318] Hardware name: Dell Inc. OptiPlex 3010/042P49, BIOS A08
12/07/2012
System environment:
--
Machine: Dell Optiplex 3010
Chipset: H61 Express
--
Distribution: Ubuntu 14.10
System architecture: x86_64
Kernel: 3.16.0-29-generic
Display connector: HDMI
--
Xserver-xorg-video-intel: 2:2.99.914-1~exp1ubuntu4.1
Xserver: 1:7.7+7ubuntu2
Mesa: 10.3.2
Libdrm2: 2.4.56-1
Libdrm-intel1: 2.4.56-1
Reproduce:
1. Connect display with HDMI and start Linux.
Additional info:
- Xorg.conf is auto generated by X, nothing modified.
I thought that it is an regression and/or an Ubuntu related problem, so I run
some tests. The result is, that Debian 7.7 with kernel 3.2.0-4 is not affected.
Unaffected systems:
- Debian 7.7 with kernel 3.2.0-4 (amd64)
Affected systems:
- Ubuntu 15.04 with kernel 3.18.0-generic (amd64)
- Ubuntu 14.10 with kernel 3.16.0-29-generic (amd64)
- Ubuntu 14.04 with kernel 3.13.0-32-generic (amd64)
- Ubuntu 13.04 with kernel 3.8.0-19-generic (amd64)
- Fedora 21 with kernel 3.17.4-301.fc21.x86_64 (amd64)
- Centos 7 with kernel 3.10-123.el7.x64_64 (amd64)</pre>
