--- Comment #8 from Pavel Roskin <proski at gnu.org> ---
I'm using Ubuntu 14.10 i386, fully up-to-date. The data is from a self-compiled
32-bit kernel. I tried compiling 64-bit kernels, it makes no difference. The
kernel config is heavily stripped to speed up bisection, but kernels with more
features exhibit the same problem.

Running "xrandr -verbose" causes extra lines to appear in Xorg.0.log. They are
present in the attached files. It's interesting that only one modeline is
printed for old kernels, whereas many modelines are printed for the new
kernels.

The data for the Linux 3.18.0-00781-g97416b3 (the latest
intel-drm/drm-intel-nightly) is very similar to the data for the first bad
commit (0e32b39ceed665bfa4a77a4bc307b6652b991632), so I'm not attaching it.
