3.7 radeonfb broken on efivga screens
Submitted by Vladimir
Assigned to Default DRI bug account
stock 3.5 kernel and 3.7-rcX ppa kernel
booting via efi with grub2
ati cards have broken framebuffer on 3.7 (all is fine on 3.5)
tried 2600xt, 6870, 6970 (all have efi part in rom, showing efi boot screen)
on 3.7, when radeonfb activates, I see for a moment two sides of screen (left and right) swapped (not mirrored), then(when X start) only very few lines on top of screen is actualy showing something(I can see part of mouse pointer there), rest is filled with one color.
Same result with all cards I mentioned.
