OK, though I'm still worried about the kernel warning (which happens before
Xorg loads, so it is not caused by usermode).

Anyway, off to living dangerously - got the very latest sources (at least I
think I did: git clone
http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/).

They compiled OK (with plenty of warnings, mostly about overriding 'const').

Copied the new binaries to /usr/lib (carelessly, while X was running - and
crashed Xorg, :P ).

Same result - nothing on gdb, display freezes quickly when dragging around a
large window. Same 'stuck on render ring' messages (once before the GPU crash
message and then repeated many times after that). This time, it did not recover
even partially and remained frozen solid (or I did not wait long enough - I
rebooted after 10 minutes or so).

I also got the kernel warning in drivers/gpu/drm/i915/intel_display.c (some 7
minutes after the 'freeze' - could have been because video went to sleep
though, not necessarily related to the 'stuck ring' problem).

Saved new drm/card0/error file (I will attach it, bzip2-ed this time).
