Hi Daniel, On 3.9-rc1, I get the following warning on my MacBook Pro Retina. Graphics still seem to work ok, but I think that's because it's really using the nouveau driver instead of the intel driver (so David says). Anything I can do to test to try to fix this? thanks, greg k-h [ 6.000101] Console: switching to colour frame buffer device 360x112 [ 6.006662] nouveau 0000:01:00.0: fb0: nouveaufb frame buffer device [ 6.006664] nouveau 0000:01:00.0: registered panic notifier [ 6.006668] [drm] Initialized nouveau 1.1.0 20120801 for 0000:01:00.0 on minor 0 [ 6.006756] snd_hda_intel 0000:01:00.1: enabling device (0000 -> 0002) [ 6.006838] hda_intel: Disabling MSI [ 6.006868] hda-intel 0000:01:00.1: Handle VGA-switcheroo audio client [ 6.007848] [drm] Memory usable by graphics device = 2048M [ 6.007867] i915 0000:00:02.0: setting latency timer to 64 [ 6.031217] usb 2-1.8.1.2: USB disconnect, device number 7 [ 6.043198] i915 0000:00:02.0: irq 49 for MSI/MSI-X [ 6.043204] [drm] Supports vblank timestamp caching Rev 1 (10.10.2010).
