Bug#655152: patch for "[drm:intel_prepare_page_flip] *ERROR* Prepared flip multiple times"

["Sten Heinze" <shze@gmx.de>]

Hi,

Please backport the patch merged in Linux to the Debian kernel. The patch is in 
the upstream 3.5 kernel and references the bug freedesktop.org bug report:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=c2798b19bac2538393fc932bfbe59807a4734b3e

https://bugs.freedesktop.org/show_bug.cgi?id=41793#c5

With the current Debian kernel (I'm using 3.2.21-3) without the patch, I still 
get lots of messages of "drm:intel_prepare_page_flip] *ERROR* Prepared flip
multiple times" which increased the size of the log files to gigabytes within 
a few days:

-rw-r----- 1 root adm  489M Aug 18 11:26 syslog
-rw-r----- 1 root adm  487M Aug 18 11:26 kern.log

Thanks,
Sten
