full kernel 3.5rc2 log

Screen on my Samsung R50 notebook with AMD Mobility Radeon X300 (RV370 chipset)
become completely unusable after resume (watch screenshots). I've tested
different kernels from 2.6.32 till 3.5rc2. Just the same thing. The thing
happens only with KMS turned on. I have tried suspend from X (Xfce) and from
console (using pm-suspend).


I repeatedly get following errors in kernel log after resume:

I recognize that I have really old notebook, but It has enough power for my
tasks so it will be good to use KMS on it cause I loose a lot of features of X
without it.

[Bug 43441] [RADEON:KMS:RV370:RESUME] garbage on screen (console or X) after suspend-resume with radeon (KMS only)

--- Comment #4 from Adrian Knoth <adi@drcomp.erfurt.thur.de> ---
I can report similar (same?) garbage with the following device:

01:05.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
RS482M [Mobility Radeon Xpress 200]


Kernel version is 3.11.

While UMS always used to work, KMS is causing trouble.


Note that garbage goes away when I plug in the A/C power supply, in other
words, it only happens when running on battery.

I've added two videos showing the corruption:

   http://adi.loris.tv/radeon-kms1.mp4

   http://adi.loris.tv/radeon-kms2.mp4


I guess it's PM related, since radeon with KMS sometimes fails to properly
resume/suspend, but I haven't noticed a reproducible pattern. As a rough
estimate, first suspend/resume cycle works, second almost always fails. If not,
then the 3rd will.

Please make sure your kernel has these patches:

The second commit was already part of 3.11, but I had to add the first one.

I'm afraid it doesn't change a thing, the machine still hangs when I try to
suspend for the second time.

Garbage after first resume when on battery, no garbage when A/C connected.


Possibly unimportant observation: When I suspend a freshly booted system, that
is, when I suspend at the kdm login prompt, resuming the machine won't bring
the kdm screen back, but a black screen with a working X cursor. Restarting kdm
makes it work again. Of course, the next suspend then fails, too. (just to be
clear)

cyberbat: As mentioned in <https://bugzilla.kernel.org/show_bug.cgi?id=67121>,
I'm not sure if I'm seeing the same or a different bug.

Could you try to run some kind of cpuburn (there's a Debian package ) to see if
it fixes the output? If not, it's likely a different issue.

TIA
