On my HP mini laptop (1 GB RAM - 4 GB swap), running Mageia 5:
[ 49.872] (II) intel(0): Using Kernel Mode Setting driver: i915, version
1.6.0 20150327
[ 49.918] (--) intel(0): Integrated Graphics Chipset: Intel(R) 945GME
when loading multiple apps (LibreOffice + firefox in KDE), I have memory used
most completely and a bit of swap. In these conditions, I get lines on the
screen appearing in the menu bar of LibreOffice, or completely on the screen
preventing me from seeing anything. While looking for a log, I found these
indications in dmesg which invited me to create that BR:
[ 191.704121] [drm] stuck on render ring
[ 191.710428] [drm] GPU HANG: ecode 3:0:0x7fffffc1, in X [1755], reason: Ring
hung, action: reset
[ 191.710436] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 191.710440] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 191.710443] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 191.710447] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
