If 3.4.3 works and 3.5 fails then that is a big help as it narrows the
possible range of causes down quite a bit.

Hardware info would be helpful here but I suspect it may be a case of
doing a set of test builds to identify the offending patch.

Also anything in the log might be helpful including doing the runs with
drm.debug=255 in the kernel command line to get full traces
