> no longer affects: linux (Ubuntu Precise) This is not true. I have this bug on 12.04:
[ 8.485683] [drm:intel_dp_set_link_train] *ERROR* Timed out waiting for DP idle patterns [ 8.485684] [drm:i915_write32] *ERROR* Unknown unclaimed register before writing to 64040 uname -a Linux laptop 3.8.0-34-generic #49~precise1-Ubuntu SMP Wed Nov 13 18:05:00 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1138700 Title: Using eDP leaves kernel log with "Timed out waiting for DP idle patterns" messages Status in HWE Next Project: Fix Released Status in The Linux Kernel: Fix Released Status in “linux” package in Ubuntu: Fix Released Status in “linux” source package in Quantal: Fix Released Status in “linux” source package in Raring: Confirmed Bug description: [Impact] * This confuses end users. They think that this is a relevant message instead of an unimportant accident to the eDP [Test Case] * Use an eDP haswell system * See this message in dmesg [Regression Potential] * Low. This patch just skips a port check on eDP machines * It has already been tested on eDP machines [Other Info] * private bug 1097143 [Original message] eDP on haswell graphics puts some stuff in dmsg that is scary to users. Worse, these messages are displayed on suspend/resume, and because we don't have vt-switchless resume support in ubuntu yet, when the graphics don't work it seems like these messages are the culprit.
