3.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Maarten Lankhorst <maarten.lankhorst@canonical.com>
commit f934ec8c34b9dcefb5a4f35b0bda33bca289cbe6 upstream.
My cheapo monitor has an invalid block 1, resulting in a lot of dmesg spam every few seconds.
I get it the first time that the entire block is all 0xff..
