--- Comment #26 from Andreas Loew <awl1 at gmx.net> ---
Hi again,

sorry, it took longer than needed for me to find my way through compiling
recent kernels with rpmbuild and an appropriate spec file.

The result of my testing is negative: The bug is still included in the most
recent 3.13-rc3 kernel... :-(

>From the attached dmesg output (which in both cases, includes the time when the
issue was seen and my screen was completely garbled), it looks to me that there
are no signs - not even in debug mode - of anything going wrong, so if I am
right with this assumption, I think this supports your theory that the root
cause of the severe screen corruption indeed is a "fencing" issue...

In the meantime, I have created a git repository on my machine and produced two
3.6-based tarballs for before and after the "mega patch".

I will now move forward to adapt a 3.6 kernel rpmbuild spec file and then build
two kernels for these two snapshots.

I should be able to update you on my progress some time tomorrow...

Thanks & best regards,
Andreas
