Bug#586485: Some observations
-----BEGIN PGP SIGNED MESSAGE-----

Hi,
Can I add some observations to this bug report.
I have what appears to be the same problem. I've had a some difficulty
getting radeon to work with much of the problem caused by a conflict between
vesafb and radeondrmfb. It seems grub likes to use vesafb if it gets half a
chance. Not using GRUB_GFXPAYLOAD_LINUX is helpful.
However it all now pretty much works except if I suspend (pm-suspend). When
resuming from suspend, the display is not restored. It stays black and
nothing I've tried can coax it into action. Apart from the display the system
is working normally.
If I hibernate (pm-hibernate) the display resumes properly. So having resumed
from suspend and got the black screen if I then hibernate and resume it all
recovers back to where it should be.
To me this points to some sort of initialisation issue when resuming from
suspend. My guess it's being re-initialised by the reboot after hibernating
but that doesn't happen when resuming from suspend.
I hope that's interesting.
