Xorg log
I've just noticed that the first resume does not work properly. In fact, if, after the first suspend/resume, I switch to a virtual terminal I see the same video corruption I experience during the second suspend. Switching back to X fixes this corruption (but not always, at least in one case I was unable to switch back to the X session and I had to reboot the system). Moreover after the first resume I can't logout from X. When, after the resume, I try to logout I see a garbled screen and the system hangs. If this can help I attach the dump of the video registers before and after the suspend. The dumps are obtained using this command: ./avivotool regmatch '*' > file Created attachment 32856 [details]

Registers after the suspend
With Linux 2.6.34 and KMS suspend-to-ram works fine! I think the bug can be closed. Thanks guys for your work! |

Created attachment 32026 [details] Image of the garbled screen I've a Toshiba Satellite with Radeon Mobility X1600 (M56P). I've some problems with the suspend/resume: - the first suspend/resume works fine (I suspend the system with "pm-suspend"); - when I try to suspend for the second time the screen becomes garbled and the system hangs (is does not enter in the suspend state). The system does not respond and I have to shutdown the laptop holding down the power button for a few seconds. I'm NOT using KMS, kernel version 2.6.32 with drm-radeon-testing. 01:00.0 VGA compatible controller: ATI Technologies Inc M56P [Radeon Mobility X1600] Let me know what kind on additional information do you need. Thanks!
