gpu error log

This is happening very frequently on an Intel Celeron 2955U system.  Most often Chrome triggers it but kwin_gles can as well (these are the only 2 hw accel apps I really ever run on this host).

xf86-video-intel version is 2.99.917.  This problem was happening on 2.99.916 and earlier 2.99.9xx versions too.

I've tried switching between sna and uxa, turning tear free on and off, nothing seems to mitigate it.

Attached is the last /sys/class/drm/card0/error
