Title:
[radeon] screen corruption on resume from hibernate, then cycles
between blank and corrupted screen
Status in “xserver-xorg-video-ati” package in Ubuntu:
Expired
Bug description:
Binary package hint: xserver-xorg-video-ati
'lsb_release -rd'
Description: Ubuntu 10.04 LTS
Release: 10.04
[I'm using Kubuntu]
Using the radeon driver, (standard lucid install), with the Radeon HD 4550
GPU [RV710], on resuming from hibernation, the following happens:
- Splash screen shows resume happening as expected
- Screen turns black for a moment
- Complete corruption, with grey lines etc. appears on screen.
- After a short while the screen then starts cycling between a black screen,
and a black screen with some corrupted areas. When I move the the mouse, I can
see a blue rectangle moving around the screen, this is only visible when the
corrupted areas are showing. If I try switching to the terminal (Ctrl + Alt +
F1) it sometimes switches directly, and properly, but then also starts the
above cycle, with the terminal then showing more towards the centre of the
screen when the corrupted areas are showing. (Sometimes it directly shows the
corrupted terminal, without showing it the way it should be first.) Some error
lines as follows can be seen on the terminal (A full extract from kern.log from
resume is attached with all the messages):
Jun 16 21:27:44 andrew-desktop1-ubuntu kernel: [ 126.360077]
[drm:radeon_fence_wait] *ERROR* fence(ffff8800377e2080:0x00005D11) 510ms
timeout going to reset GPU
Jun 16 21:27:44 andrew-desktop1-ubuntu kernel: [ 126.360089] radeon
0000:01:00.0: GPU softreset
It is possible to control the system, although difficult due to the
switching, from the terminal, pressing the power button however starts a
shutdown. This then brings back the splash screen (which shows properly), after
which the system switches off.
Expected result: The splash screen is shown, then Xorg is restored
with the unlock dialog showing.
Note: When I do a suspend to ram, immediately before switching to the
unlock dialog I get a fully corrupted screen, similarly to when
resuming from hibernation, for a moment.
Note2: When using fglrx hibernate and suspend work fine, however the
splash screen is only at 640x480 resolution, and some slight
corruption is shown on screen before showing the unlock dialog. (The
fglrx driver also seems to make my system slower.)

As far as I can tell this is a bug in the radeon driver, since it
doesn't occur with the proprietary driver.
- I will get photos and videos up tomorrow (time-permitting) detailing
what happens.
