I've got a JVC/Asus MP-XV841 laptop which mostly works great with Fedora Core 3 except for suspending/resuming. Using the kernel boot parameter "acpi_sleep=s3_bios" lets the notebook suspend and resume, but DRI doesn't survive properly and if any 3D application is run after a resume I get wither: * An X server hang that requires shutting down the machine (the machine is still running and responds to acpi events, so I can shut down the machine). This happens with armagetron or celestia. * The application draws its first frame, freezes a few seconds, then crashes without taking the X server with it. (the GL screensavers, glxgears do this). When this happens, I get an error message in the console after the app crashes: $ glxgears intelWaitIrq: drmI830IrqWait: -16 This also puts a single line into the system logs. dmesg gives: [drm:i915_wait_irq] *ERROR* i915_wait_irq: EBUSY -- rec: 0 emitted: 7 If I kill the X server and restart it, 3D works fine again, but what good is suspending if you have to restart all your apps? This hack: http://www.mail-archive.com/dri-devel@xxxxxxxxxxxxxxxxxxxxx/msg21138.html ... keeps the machine from crashing with armagetron/celestia and lets GL applications run without killing and restarting , but they all run at about 1/3 the speed they ran before suepending/resuming. This is better than nothing, but it's not optimal when I need to show some 3D molecular models to my students in class and DRI doesn't work. Unfortunately, trying to install the CVS drm modules as suggested later in the thread only makes the problem worse (kernel panic on suspend). My laptop has 82852/855GM graphics, and uses the i915 module fot DRM (that seems to be where the trouble is - I *think*). Does anyone else with Intel video experience these suspend/resume problems? I wanted to try and get as much info as possible on this before submitting it to bugzilla ... (Also, does 3D and suspend/resume actually WORK for anyone with a similar graphics chipset? I hear that Ubuntu's patched the kernel so the DRM modules wake up properly, but I'd hate to have to learn Ubuntu and drop Fedora just for this one issue...) -- -------------------------------------------------------------------- * Charles Taylor <tomalek@xxxxxxxxxxxxxx> * Chemistry instructor / Mad scientist / Linux enthusiast! -------------------------------------------------------------------- * Web: http://home.mindspring.com/~charletiv/ --------------------------------------------------------------------
