DELL XPS 13 9360 Ubuntu 16.04 keeps freezing

Just got an XPS 13 9360 on 23th of Januari 2017. On the first day it froze 3 times in 6 hours while just doing plain browsing. I disabled C States in the BIOS. Since then it freezes less frequent, about once a day. I am wondering if this is a software issue or maybe some piece of hardware that is behaving flaky.

Did you do a software update just before these problems arose?

I have the XPS 13 9360 as well, with Ubuntu 16.04 on it out of the box. It worked very well, until I started using a Thunderbolt 3 dock. Now it constantly freezes. Sometimes it just randomly freezes and it always freezes after it wakes up from suspend. I'm talking about a complete freeze. Black screen. Ctrl + Alt + F1/F2 or whatever doesn't work. Disconnecting or reconnecting the TB3 dock doesn't work. I have to force shutdown by pressing the hardware power button for a few seconds. I have the latest BIOS (1.3.2).

Same thing here, with the exception that I've upgraded to 17.04, and I use a USB-C dock.

Same here (17.04), also using latest mainline kernel (4.12.8). Nothing seems to improve this issue. Nothing in the logs to go on, just freezes randomly and requires a hard reset. Really disappointed, to the point I'll be installing Windows on it and using a VM.

I got the 9360 as well earlier this year, but do not experience this issue at all. For the record, I use an external monitor via USB-C.

I have the same problem. My dell 9360 freezes, so I have to hold power button untill it shuts down, nothing else works. I regularly update in a hope that it will get fixed, but nothing happens.

Original post was posted in January, but we still have no reply from dell. Is dell even monitors this forum?

Hi!

Dell support obviously does not monitor this forum. I contacted support by mail and they do not even know Dell sells laptops with Ubuntu installed. I had to explain that I bought the laptop straight from Dell with Ubuntu installed and that the problem existed without any modifications from my side.

I do not know what is the exact cause for this problem, but my freezes stopped after updating the BIOS and apt.

See: www.dell.com/.../updating-the-dell-bios-in-linux-and-ubuntu-environments

Hope this helps. Good luck.

BIOS updates are automatic in Software center, you have to reboot though. I updated regularly, but it did not help for me. After some googling I've decided to update kernel and so far I had no freezes for couple of days.

Run 

sudo apt install xserver-xorg-hwe-16.04


It completed with errors, but kernel version changed to 4.10.0-35-generic. 

Run:

uname -r 

to check

My laptop just froze again. So updating kernel doesn't really solves the problem.

Did you try to update the BIOS?

All I know is that the freezes on my XPS 13 stopped after updating the BIOS and all the software packages.

Yes. I updated BIOS through "Ubuntu Software".

I just checked, I have the latest version of BIOS. It might be hyper-threading bug, I've turned it off yesterday in BIOS. I am now waiting if I will get another freeze or not.

So I think I have finally found what was causing freezes. I changed unity desktop environment to KDE plasma and random freezes finally stop. I have also found that Dell already adressed hyperthreading bug on kaby lake processors in their 2.2.1 BIOS.

Hi there, could you verify that this indeed solved the problem?
I would like to avoid having to use the KDE environment, but I'm getting quite desperate to fix this problem.
Thanks!

I have been struggling with, what I think, is the same issue as you guys.

Updating the docking station drivers was impossible for me, and updating the linux kernels didn't do the trick.
What did work, however, was disabling the Realtek r8152 LAN driver's auto-suspend feature.
