cat /sys/class/drm/card0/error | bzip2 > error.bz2

It happened again, similar scenario - resuming from suspend and instead of
lockscreen there's only wallpaper and mouse cursor. But this time I had
xf86-video-intel installed and it did somewhat recover. After switching to
another tty and back a textbox for password appeared and I could type but
characters would appear with few seconds delay. After logging in desktop is
partially broken - for example Chrome doesn't redraw window content unless it's
resized, some KDE menus are broken, etc.

I'll attack the logs, but this happened with kernel 4.8.3, so I don't know how
useful they will be. I did build drm-intel kernel using this -
https://aur.archlinux.org/packages/linux-drm-intel-nightly/ - but it wouldn't
boot (couldn't find root device for some reason) and I didn't have time to make
it work.
