Hello,

I get an issue with mac book pro retina with git snapshot of kernel[1].
the screen flickering like this http://www.youtube.com/watch?v=Oq0l-bHmSYE

anyone has an idea where the issue can come ?

if not this could be a bug report ^^

the flickering is more visible on screen update, like refresh firefox page.

Best regards

Hello,

After a day of try kernel 3.6.0-rc6 with following parameter :
maxcpus=8 nouveau.force_post=1 nouveau.noaccel=0 acpi_osi=Linux
i915.lvds_channel_mode=2 i915.modeset=1 i915.i915_enable_rc6=1
i915.i915_enable_fbc=1 i915.lvds_downclock=1 drm.vblankoffdelay=1
i915.i915_enable_ppgtt=0 quiet add_efi_memmap root=/dev/sda4 the screen
do not blink anymore.

I do not know if the issue is solved by kernel patch between 3.6.0-rc6
and 2 day before 3.6.0-rc6 or if this parameters solved the issue. (last
e-mail report was about kernel 2 day before 3.6.0-rc6. with no i915
parameters)

Best regards.
