Is the display back before the freeze ? Sadly the video *never* comes back and stays dark no matter what I try: - boot-radeon (int10 POST call) doesn't work. Either it segfaults or it hangs the machine - Any combination of radeontool light on|off doesn't help (no freeze, sometimes it can't read the cards mem address??) - The int10 radeon patch for X11 doesn't help (freeze) - radeonfb and / or X (either patched w/ int10 or not) freeze the machine I'm running out of ideas with this darn thing. Since the serial port doesn't come back from S3 either, even a serial console is of no help. I have attached the output of lspci -vvv before and after resuming from S3 The latter shows lots of "[disabled]" entries. Is that of any use?
