The PGRAPH messages listed are harmless and do not cause your issues :)

Although there are a few things you can do

1. Find out which component did you update when the issue occurred
* The game, X, xf86-video-nouveau, mesa, kernel ?

2. Check if the software renderer produces the same result
* export LIBGL_ALWAYS_SOFTWARE=1 && savage...

3. Attach better logs

Unfortunately I can't remember. I'd been using proprietary driver before
today
as I didn't get luck with nouveau.

Same result

If X crashes while using the swrast (i.e. when LIBGL_ALWAYS_SOFTWARE is set),
then the issue is not nouveau but mesa related.

If you're interested in getting this sorted you could track the package and
commit that caused this :) Hint - seems like the package is mesa and/or
xorg-server

[  4863.494] (EE) Segmentation fault at address 0xde5

This is likely a simple null pointer dereference. Install the debug versions of
the libraries (xf86-video-nouveau, mesa, X), and run X inside gdb (or just use
gdb to look up where in the code it's dying based on the addresses it
prints).

Not sure about the assertion that LIBGL_ALWAYS_SOFTWARE=1 + X crash = not a bug
in nouveau. There's still the ddx...
