I wanted to remind, that the interlaced modes work with the noveau driver with the 3.0.0 Kernel. Do they ignore the kernel routines and have their own code ? [ 18.242858] [drm:drm_mode_debug_printmodeline], Modeline 28:"1920x1080i" 0 74250 1920 2008 2052 2200 1080 1084 1094 1125 0x40 0x15 [ 18.242861] [drm:drm_mode_prune_invalid], Not using 1920x1080i mode 7 [ 18.242863] [drm:drm_mode_debug_printmodeline], Modeline 27:"1920x1080i" 0 74250 1920 2448 2492 2640 1080 1084 1094 1125 0x48 0x15 [ 18.242865] [drm:drm_mode_prune_invalid], Not using 1920x1080i mode 7 At this point, does the drm driver call kernel routines and decide on your mentioned kernel routines return to ignore those modes ?
