Hello everyone i was using the 2.19 intel driver than they released the current 2.20 version and when i enable SNA aceleration the video starts flickering and etc. I also tested 2.20.1 driver and the error continue.

Can you please quickly check whether this only affects OpenGL content (such as gnome-shell) by enabling fallback mode?
This affect fallback mode too.

Hmm, the corruption will be fixed with commit 8c5077e4ed055a97bf9deda59c0e9a45e42317ca Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Jul 25 16:59:11 2012 +0100 Assume all unknown chipsets are future gen I think the likelihood of a new product being launched based on a 8xx design is remote enough not to worry about. but... The question is why does it think your hardware is unsupported... Can you please paste lspci -vvn?
Oh and attach a drm.debug=0xf dmesg from when X starts please.
And third time lucky, an --enable-debug=full Xorg.log would be very useful as well.
Ok, this is very odd as well: [ 13.228] (==) ServerLayout "X.org Configured" [ 13.228] (**) |-->Screen "Screen0" (0) [ 13.228] (**) | |-->Monitor "Monitor0" [ 13.244] (**) | |-->Device "Card0" [ 13.244] (**) |-->Screen "Screen1" (1) [ 13.244] (**) | |-->Monitor "Monitor1" [ 13.244] (**) | |-->Device "Card1" [ 13.244] (**) |-->Screen "Screen2" (2) [ 13.244] (**) | |-->Monitor "Monitor2" [ 13.244] (**) | |-->Device "Card2" [ 13.244] (**) |-->Screen "Screen3" (3) [ 13.244] (**) | |-->Monitor "Monitor3" [ 13.244] (**) | |-->Device "Card3" [ 13.244] (**) |-->Screen "Screen4" (4) [ 13.244] (**) | |-->Monitor "Monitor4" [ 13.244] (**) | |-->Device "Card4" [ 13.244] (**) |-->Screen "Screen5" (5) [ 13.244] (**) | |-->Monitor "Monitor5" [ 13.245] (**) | |-->Device "Card5" [ 13.245] (**) |-->Screen "Screen6" (6) [ 13.245] (**) | |-->Monitor "Monitor6" [ 13.245] (**) | |-->Device "Card6" [ 13.245] (**) |-->Screen "Screen7" (7) [ 13.245] (**) | |-->Monitor "Monitor7" [ 13.245] (**) | |-->Device "Card7" [ 13.245] (**) |-->Screen "Screen8" (8) [ 13.245] (**) | |-->Monitor "Monitor8" [ 13.245] (**) | |-->Device "Card8" [ 13.245] (**) |-->Screen "Screen9" (9) [ 13.245] (**) | |-->Monitor "Monitor9" [ 13.245] (**) | |-->Device "Card9" [ 13.245] (**) |-->Screen "Screen10" (10) [ 13.245] (**) | |-->Monitor "Monitor10" [ 13.245] (**) | |-->Device "Card10" [ 13.245] (**) |-->Screen "Screen11" (11) [ 13.245] (**) | |-->Monitor "Monitor11" [ 13.246] (**) | |-->Device "Card11" [ 13.246] (**) |-->Screen "Screen12" (12) [ 13.246] (**) | |-->Monitor "Monitor12" [ 13.246] (**) | |-->Device "Card12" [ 13.246] (**) |-->Screen "Screen13" (13) [ 13.246] (**) | |-->Monitor "Monitor13" [ 13.246] (**) | |-->Device "Card13" I doubt you have quite that many monitors and integrated graphics. Can you please regenerate your xorg.conf, even better would be not to have one, but a snipped to enable sna (if using AccelMethod).
not to set a bug with non-default option as high priority

Chris i can not post the Xorg.log with enable debug full the archive has more than 180mb in 60 seconds. Now is everything running ok, i build the driver with: ./configure --prefix=/usr --enable-sna --with-default-accel=sna so i dont need a xorg.conf. Xorg.log = http://pastebin.com/LVbU7f8K
(In reply to comment #10) > not to set a bug with non-default option as high priority Sorry Gordon that was a mistake.
Still puzzling over which allocation failed to cause it disable acceleration, but at least the pair of bugs that lead to the situation have been resolved.
