Last known good: 2.6.35
Failing kernel: 2.6.36-rc1

During boot kernel display this message:
[    0.831906] [drm:intel_calculate_wm] *ERROR* Insufficient FIFO for plane, 
expect flickering: entries required = 36, available = 28.
[    0.895058] [drm:intel_calculate_wm] *ERROR* Insufficient FIFO for plane, 
expect flickering: entries required = 36, available = 28.
[    0.895066] [drm:intel_calculate_wm] *ERROR* Insufficient FIFO for plane,

Systems seems work OK, but in 2.6.35 I don't have this message. On another 
system with 2.6.36-rc1 kernel I have the same message.
