kernel-bug-exists-upstream-4.7.04-rc4

this kernel was tested:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7-rc4-yakkety/linux-headers-4.7.0-040700rc4-generic_4.7.0-040700rc4.201606201235_i386.deb

Notes:
I have tested it a few times. It is getting better.
Before 1 out of 15 no black screen
When black screen, also no keyboard lights on caps lock

Now, I only tested it about 5 times and 2 times black screen with no
keyboard.
