2.6.29-rc3+git macbook pro1,1 garbled display on resume

[Soeren Sonnenburg]

Hi,

the macbook pro suspends just fine, but even though the machine returns
to X I see on resume some random garbled output but can still move the
mouse cursor (which is OK!) and using the keyboard successfully adjust
the brightness of the display.

However I cannot switch to the console (via ctrl+alt+f1) nor does ctrl
+alt+backspace do anything....

This is on debian sid with the latest xorg radeon driver from
experimental, i.e. ii  xserver-xorg-video-radeon
1:6.9.0.91-1.

Any ideas?

Same here with jaunty i.g.
one week it worked then the next it didn't.
maybe disabling hotplug with xorg.conf
might make the keys work.

I recognized that everything seems to work just fine *on console only*.
At least I could suspend and resume via s2ram >3 times in a row.

What also worked was to just start plain X (no window manager or
anything) and suspend/resume then. However with compiz running I am
seeing the garbage/hang on resume.

Are you by chance to having an ATI card + use a compositing window
manager?

At the moment I don't have compiz manager
running, only fluxbox. But after thinking,
I did experience this(choppy screen)when using kexec,
i.g. starting a new kernel from a terminal inside the xserver
did create a messed up screen. Then(ctl+alt+del)disabling
the xserver, made things work the way they were supposed too.

I am running radeon on a macbook pro. If I can remember
at the time I was using kexec I did have radeon.(I'll try and reproduce 
this though).
In any case I think this is an xserver issue not a kernel(but thats just 
a guess).
I added a cc (hopefully it's the right one);

Could be... I've tried with a more recent radeon driver, i.e. 
xserver-xorg-video-radeon    deb-version        1:6.10.0-2 - same thing.

Is anyone aware of a known-to-work radeon version that I should try?

I'm running everything from jaunty
(with an exception of a few packages from sid "s2ram");
As for the screen being garbled, I have not see this
with s2ram yet.(although I need to see if I can recreate
this with kexec);

here's the entry for xorg.conf:

Section "ServerFlags"
     Option "AutoAddDevices" "False"
EndSection
