Hello
Aftertrying to leave an xlock started with xlock -nolock +use3d -mode
gears, I get a drm stuck on render ring error.
The funny thing is this problem did not happen on the exact same thinkpad
x201 laptop using an identical xorg.conf but with a debian jessie i386 (I
did a clean reinstall of debian jessie amd64)
xorg.conf contains:
Section "Device"
Identifier "i950"
Driver "intel"
BusID "PCI:0:2:0"
Screen 0
Option "AccelMethod" "SNA"
Option "FallbackDebug" "true"
EndSection
I'm using kernel 3.14.25, and I saved /sys/class/drm/card0/error and
gpucrash in case it's not a know bug.
Any suggestion?

It's impossible to tell without the complete information
(/sys/class/drm/card0/error, dmesg and Xorg.0.log) but it sounds like
the kernel bug: https://bugs.freedesktop.org/show_bug.cgi?id=87780
