Xorg breaks apm suspend to RAM
Last modified: 2007-11-30 17:10:54 EST
Description of problem: Apm suspend to RAM worked fine in xorg in FC2 but now seems to be broken in FC3. Any attempt to resume from suspend now results in a hard lockup of the computer if xorg is running at the time of suspend. Switching to virtual consoles prior to suspend does not help. However the problem is much more serious than that. Suspend to RAM works fine if I boot to runlevel 3 (no xorg). If I then start and stop the x server (and double check to make sure all processes and kernel modules are back to what was running prior to starting x), I am back to the hard lockup problem on resume. Version-Release number of selected component (if applicable): Am using xorg-x11-6.8.1-12 kernel 2.6.9-1.667 with the radeon driver on a Dell Inspiron 4150 laptop, which uses a radeon mobility 7500 graphics card. How reproducible: Every time Steps to Reproduce: 1. Boot to runlevel 3, and log in 2. Apm suspend to RAM works fine 3. startx 4. crtl-alt-backspace Actual results: Resume from Apm suspend gives a hard lockup Expected results: Should work fine as it did in FC2 Additional info:
I dropped back to version 6.7 which fixed the problem. Unfortunately I won't be able to help with further testing.
One further note: I tried going back up to xorg-x11-6.8 and only copying radeon_drv.o and ati_drv.o from version 6.7 back. This also fixed the problem with suspend, so now it should be easier for me to test any proposed solutions :)
Seems to be fixed as of the most recent xorg-x11 update 6.8.1-12.FC3.21 Thanks
I'm having a very similar problem with my Dell 600m. When I resume, the display is completely corupted. The screen starts out black and then white spreads out on it, like milk spilled on it. Within about 10 sec the entire screen is white. It's very strange. I asked what it was on the Linux on Dell Laptops Yahoo mailing list and got the response that it was a known problem and a patch was dropped from FC2 to FC3 for some reason. I've attached the patch he gave me. Is this already applied? Do I have a completely diffrent problem?
Created attachment 109021 [details] Possible fix for Radeon Screen corruption on APM Resume Is this patch already applied in the latest xorg update (xorg-x11-6.8.1-12.FC3.21)?
In reply to comment #3: Thanks for the feedback David. We also will be releasing 6.8.2 for FC3 soon, which has additional fixes for radeon. In reply to comment #4 & 5: Please test the latest erratum for FC3, and if the problem persists, upgrade to the xorg-x11-6.8.1.901 or newer release from rawhide, as that is ultimately what will be the next update release for FC3 as well. After testing this, should the problem persist for you, then it is not the same problem described by the original reporter in this report. In that case, file a new bug report in freedesktop.org bugzilla at http://bugs.freedesktop.org in the "xorg" component and attach your X server log and config file as individual file attachments in Xorg bugzilla. This will allow X.Org developers to be aware of the problem if it persists, and potentially to fix it sooner. Setting status to "ERRATA"
