<pre>I'm using radeon driver for my Radeon HD 4200 (integrated chipset/laptop).
=> RS880
Suspend to RAM (s2ram) was working well with kernel 3.14.x
Problem starts with 3.15.
After resuming I have an unstable system.
symptoms:
- Last 6 pixel lines (botton) on screen are black (even the mouse cursor isn't
drawn)
- playing fullscreen video (vlc) for a very few seconds: black screen but with
cursor, no keyboard actions possible. Freeze.
- switching to console CTRL-ALT-F1: sometimes screen garbage, keyboard is
working. (blind typing)
workaround:
- restart X (init 3 or logout from KDE)
- change screen resolution (with e.g. kscreen). This makes the system stable
until next reboot. Even multiple s2ram/resume cycles won't hurt now.</pre>
