<pre>System environment:
-- chipset: QM87
-- system architecture: x86_64
-- xf86-video-intel/xserver/mesa/libdrm version:
- xf86-video-intel: 2.99.914 (git commit
f36b7a4aac86f5874c32d8f516ac1f00a6c8d8b3)
- xserver: 1.15.1
- mesa: 10.1.3
- libdrm: 2.4.52
-- kernel version: 3.17.0-rc4 (built from -nightly @ 99f444f [same happens with
current nightly])
-- Linux distribution: Kubuntu 14.04
-- Machine or mobo model: Lenovo ThinkPad T440p 20AN
-- Display connector: DVI, DisplayPort
3) Reproduce steps:
When logging into KDE the login progress comes to a halt for ~ 15-30s and the
following is logged to dmesg:
[ 69.722297] [drm] no progress on render ring
[ 69.723011] [drm] GPU HANG: ecode -1:0x00000000, reason: Ring hung, action:
reset
[ 69.723014] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 69.723015] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 69.723016] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 69.723017] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 69.723018] [drm] GPU crash dump saved to /sys/class/drm/card0/error
I tried bisecting the problem, but due to <a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED FIXED - [HSW regression bisected] kernel lockup during early boot"
href="show_bug.cgi?id=83166">bug #83166</a> this does not work too
well...
Earlier nightly builds did not suffer from this problem, AFAICS 52addcf is ok.</pre>
