Kernel messages
Hello, I have a similar problem as the one described here.
I have a ThinkPad x230 with the following graphics card:
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor
Graphics Controller [8086:0166] (rev 09)
The monitor is an ASUS PA248Q, connected to the computer using a
MiniDisplayPort to DisplayPort cable.
I've also been experiencing freezes, and the kernel regularly prints
stack traces like the ones you can see in the attached log.
This happens when I turn the monitor off (using the power button)
while the cable is connected.
I generated the log using the patch from <a href="show_bug.cgi?id=81537#c19">comment #19</a>. The kernel is from
Debian:
Linux 3.16.0-4-amd64 #1 SMP Debian 3.16.7-2 (2014-11-06) x86_64 GNU/Linux
Reverting the patch mentioned by Adam also makes my system more stable.</pre>
