First report on SNA: I got a very very strange thing yesterday. After
resuming from suspend-to-ram I continued working with GIMP on some
graphics, and first it started with some blue flashes on the screen, and
finally the screen got completely blue, but I could in principle still
interact with the windows, just without seeing anything.

Restarting X (gdm) did fix it for me.

Doing more heavy IO to stress test SNA.
