As I was using an old FC8, I forgot about it. But I'm now running a quite recent FC11, pure 64bit machine, and when I run a vanilla kernel, I have this message showing again and again. I propose to apply the following patch : --- drm_irq.c.orig 2009-07-26 21:36:20.000000000 +0200 +++ drm_irq.c 2009-07-26 21:36:34.000000000 +0200 @@ -566,7 +566,7 @@ ret = drm_vblank_get(dev, crtc); if (ret) { - DRM_ERROR("failed to acquire vblank counter, %d\n", ret); + DRM_DEBUG("failed to acquire vblank counter, %d\n", ret); return ret; } seq = drm_vblank_count(dev, crtc); to shut the message. This is at least what I do on my machine to have it running quietly. Anyway, if anyone care to explain why we have this "error", I'd be glad to learn about it. And if anyone wants me to test some patches, I'll be glad to.
