Hi, I have a funny situation... on a dell xps 9350 00:02.0 VGA compatible controller: Intel Corporation Sky Lake Integrated Graphics (rev 07) model name : Intel(R) Core(TM) i7-6500U CPU @ 2.50GHz with kernel-4.4.0-3.g75554c0 i get a black screen at boot... is just after grub but before systemd starts logging.. Randomly, once in 10 black screens boots. however with 4.4.0-rc7-3.g75554c0 built by me with the same configs as the 4.4.0 kernel boots every time. I do not know if this is an issue with the card... but looks like... Alin

I don't know what those kernels are; what patches do you have on top of upstream? Can you reproduce with vanilla upstream?
Hi Jani, you are right I repeated with vanilla and the same story... the diff between default and vanilla is as follow.

(In reply to Alin M Elena from comment #2) > I have built the head from Linus git and booted... Please tell me the git commit ID of the kernel you've tried from Linus' tree. Please add drm.debug=14 module parameter, and attach dmesg. If possible, please do so when you're experiencing a black screen (either ssh into the box or ensure you get the logs on disk).
this is the one I tried and booted. 5807fca with the logs may be tricky to get since when I get a black screen there is none.. and I have no network card on that machine. Alin when 4.4.0 boots I keep getting this... I suspect totally unrelated...

A have a similar yet different problem, see bug 93950. The laptop boots up just fine, but the screen dies if I restart the Xorg server.
