Description Elmar Stellnberger 2013-02-20 10:37:47 UTC

User-Agent:       Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:18.0) Gecko/20100101 Firefox/18.0

  Every time I try a userspace suspend (/etc/suspend.conf: shutdown method = shutdown) with the radeon driver loaded (no radeon.modeset=0 kernel command line) the screen starts to flash black (backlight on/off, always black) and the hibernation process hangs. Similar behaviour has already been discovered for vt-switching (Bug 803099). Happens also when pm-hibernate is invoked from runlevel 1. Normal hibernation does already work (Bug 803098).

Reproducible: Always
