Bug Description
I always get an warning and stacktrace (and it seems to hang a little bit). This occurs after reboot as well as when I move with the cursor between my hdmi monitor and my laptop. (This only occurs when HDMI is connected)

There, the cause is DP/HDMI hotplug, but the end result is the same.

on my skylake system i seem to get these warnings a lot too.
Also when using KDE i get display corruption, and hard system crashes (no network login possible anymore, and nothing written to logs)

I can confirm this, with the following setup:
- Linux 4.3.0 (vanilla source tree, built with Debian's make-kpkg, kernel config derived from Debian distro kernels)
- Debian testing (stretch), amd64
- Intel(R) Core(TM) i5-6600K CPU @ 3.50GHz
- Dual-monitor setup, one connected directly to DVI, the other attached via DisplayPort<->DVI adapter
It seems I can reliably trigger the WARN_ON(
Besides the backtrace-spam in my log, the system seems to run fine, no hangs, crashes, or the like (running Xorg from stretch with i3-wm).
I notice scrolling-related artifacts in conkeror, but that may be a totally unrelated issue.

This has also happened for the users commenting to bug: #92599 (Added as duplicate). Causes a false positive on the module reload test because the errors are spit out repeatedly even before unloading the module.

It is reproducible as it only occurs with a hdmi connected monitor, without there are no error messages/warnings.
Also X server is (sometimes) unable to start because of this

I believe I am experiencing this issue also. Dell Optiplex 7040 with Intel I7-6700 (skylake) with integrated graphics (Intel HD 530) running Ubuntu 14.04.3 LTS.
Two monitors are connected via displayport cables. Issue also occurred when using displayport to DVI adapters.
The following is logged to /var/log/syslog every time I move the mouse cursor between screens. Occasionally when I move the mouse cursor to the other screen, the screen will blank and then a few seconds later come back on. Windows are not re-arranged (implying it is not the disappearance of a screen), and similar log entries are produced. No other rendering issues or graphics issues have been noted - Unity works fine. Running tuxracer does not cause any issues.
If there is any additional information I can provide that would be helpful please let me know.

Happens also on a brand new XPS 15 9550 laptop. I tried also today's kernel git (with some drm fixes for i915).
System is installed anew with Debian testing up-to-date, latest kernel code and intel video driver 2:2.99.
Symptoms:
- system boots (lightdm)
- laptop screen blinks like crazy, monitor picture is ok (Dell P2715Q, HDMI connection)
- after logging-in everything freezes - I have to turn-off computer.
What I do to make it work:
- boot without HDMI plugged-in
- after log-in, plug-in HDMI and then I have stable environment.
This is the trace I found in syslog:

I'm pretty sure this happens because we wind up re-computing the same watermark values for each CRTC multiple times in a single atomic transaction (once per CRTC involved in the transaction). I'm putting together some patches that make SKL watermarks play more nicely with atomic (and eliminate this unnecessary looping); I should have those ready to post next week sometime.

I don't think the message is the cause of your hang. The message here is a harmless warning that we're needlessly re-calculating something we shouldn't be. That's something we shouldn't be doing (and I'm in the process of fixing), but it won't actually cause any harm or trigger a system hang.
The WARN() here will often show up any time a modeset operation happens while you're using multiple displays. It sounds like something else is going wrong for you during that modeset which does cause a hang and this message just happens to be the last thing you wind up seeing.
Could you please open a new bugzilla describing the details of your setup and any actions that trigger the hang for you? It's unlikely that fixing this message here will fix your hang, so we'll want to investigate your report separately.

BTW, I noticed that the following when the backtrace as discussed in this bug occurs on my laptop: When I switch virtual desktops the image of the window in the previous desktop is shown for some time if the current desktop does not have any windows.

I'm having the same issue, on exactly the same machine as Aljaž Prusnik in comment 31.
Machine is Dell XPS 9550 with i7-6700hq, kernel is 4.5.1 (from testing on Arch Linux, using the X modesetting driver)
When starting X with external display attached and using xrandr it
a) takes very long to apply the mode, over 5 seconds
b) very often leaves the internal display completely black
When I move the mouse when it is in this mode, it'll lockup, leaving me to only be able to poweroff the machine. When I redo xrandr without moving the mouse, and get it to work on both screens, it'll work without problems after that.
The lockups also happen after the screens wake up from DPMS power save.
It's not happening with a 4.4 kernel, but this one has other problems, like endless flickering on the external display after a DPMS wakeup.
I'm really eager to have that patch, but since the merge window for 4.6 is already over, does this come with 4.7 the earliest?
In freedesktop.org Bugzilla #89055, Freedesktop-k (freedesktop-k) wrote : | #46 |
forgot to add: If I disable HWcursor in X config the lockups completely dissappear, but sadly the cursor also disappears whenever I stop to move the mouse :/

Same in a T460p, using the Ultra Dock station connected via HDMI to an external monitor (that actually routes through DP3-1).
I see these errors multiple times, and I also experience some hangs where I see visual corruptions in monitor. Not sure this can be related, but indeed it has something to do with intel.

Note that the series linked above is fully reviewed now, but we probably want to hold off on merging it until one more issue is fixed. Apparently some BIOS can setup an unusual/unexpected initial DDB allocation that causes us problems when we try to inherit it and use it for subsequent watermark calculations. See
https:/
for details.

I don't have access to any APL machine.

Could someone please let me know how to apply this patchwork to mainstream
kernel source?
I tried on the latest 4.6-rc5 and it failed. It did work on
drm-intel-nightly though which is a not mainstream branch.

Unfortunately, while this patch (against drm-nightly 4.6.0-rc5) did eliminate the stack traces from my dmesg logs, it seems to have *introduced* a freezing bug. Every six to twelve hours or so the system freezes completely, audio stops, caps lock stops working (though it doesn't blink as in a panic). I assume this is a deadlock of some sort because there is no indication in any system logs that a freeze has occurred.
I have been having many issues related to suspend, so I thought at first this freeze was another manifestation of the same bug. But after happening four or five times, it just happened last night after several hours of being on without ever having been suspended. I can try the same kernel unpatched but I have tried a similar version before and I suspect the freeze is new.

Step 2 leads to disabling of OpenGL backend which could mean performance
might be a bit lower, but your system will be very stable and usable with
this.
Hope this info helps some folks.

Since I got a few offline questions last time, the patches here are meant to be applied on top of the drm-intel-nightly branch of git://anongit.
