Hi! I'm one of the users affected by video corruption with RC6 enabled on Sandy Bridge mobile. My machine is a Dell Inspiron 15R N5110 powered by an i3-2310M. No additional graphic card, the HD3000 is enough for my needs. What I experience can be found in this bug report: https://bugs.freedesktop.org/show_bug.cgi?id=41682 I'm rather unexpert, so I don't know exactly which data I should provide in order to help you understanding what's going on, but I'm open to learn. Cheers, Luigi -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.freedesktop.org/archives/intel-gfx/attachments/20120204/b269c80a/attachment.html>
