Critical regression in 4.7-rcX

To anyone keeping track of regressions in kernel 4.7, I call your attention to https://bugs.freedesktop.org/show_bug.cgi?id=96675.

This bug causes driver i915 to fail to connect to the display, and results in a blank screen as soon as the kernel is loaded. The only way to operate with kernel 4.7 is to add "nomodeset" to the command line. The problem was bisected to commit f21a21983ef13a ("drm/i915: Splitting intel_dp_detect").

This bug was reported on 2016-06-25 16:10 UTC, but seems to have received no attention by the Intel group. That is the reason that I am complaining here. It seems very likely that kernel 4.7 will be released with this bug, and a number of high-end Toshiba laptops will break.

Thanks,

Larry
