[Bug 1523088]
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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1523088 Title: WARN_ON(!wm_changed) warning and stacktrace in kernel log To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/1523088/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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.

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.

[Bug 1523088]
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? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1523088 Title: WARN_ON(!wm_changed) warning and stacktrace in kernel log To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/1523088/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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 :/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1523088 Title: WARN_ON(!wm_changed) warning and stacktrace in kernel log To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/1523088/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks, Matt. You are right that this is not the primary cause for the hanging.

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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1523088 Title: WARN_ON(!wm_changed) warning and stacktrace in kernel log To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/1523088/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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).
