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 bug #83166 this does not work too well... Earlier nightly builds did not suffer from this problem, AFAICS 52addcf is ok.
