I initially put this as the driver then changed it to kernel because this is when the bug occured after receiving the update. I was (made) aware of that link (not long after) changing the Component.

Oh sorry for not reading! thanks for the info. Looks like that's the only hope so far..I'll check it out as I'm still only able to use it with 4.6.7-300.. and still no luck with the Psychotic Stoned Sheep.

Created attachment 1202549 [details] intel_reg_dumper run on kernel 4.6.7-300 unable to run intel_reg_dumper and see output with kernel 4.7* !!
Am able to use with external Samsung display via the gameport/vga and have had to turn off the internal Intel i915 GM45 mobile 4, currently running Kernel-4.7.4-200 The internal display (still) only running on kernel-4.6
As a workaround, this works.. kinda! resolution is slightly off and destop eyecandy is limited or doesn't work? http://forums.fedoraforum.org/showpost.php?p=1768450&postcount=2

Fixed for me in 4.7.5-200.fc24.x86_64...
Confirmed fixed with kernel-4.7.5-200 (so it was a kernel issue!!)
(In reply to ben from comment #14) > Confirmed fixed with kernel-4.7.5-200 > (so it was a kernel issue!!) It usually is. The bugzilla component is still correct per the link already shared. Thank you for confirming it's fixed.
