[Kernel-packages] [Bug 1567417] Re: WARN_ON(!wm_changed) skl_update_other_pipe_wm+0x16c/0x180 [i915_bpo]
I have the same problem using precision 5510 + Dell dock, used to have perfectly working 3 monitors setup, which no longer works after the latest update (4.4.0-77-generic). I can no longer use 3 screen setup, 2 monitors setup is barely working and I often need to reset it after boot, reordering the screen is also impossible. I tried that with Nvidia latest drivers, with/without intel profile and the open source driver, got the same results. here is the log message: [3.104821] [ cut here ] [3.105632] WARNING: CPU: 3 PID: 24 at /build/linux-FyIZxz/linux-4.4.0/ubuntu/i915/intel_pm.c:3675 skl_update_other_pipe_wm+0x16c/0x180 [i915_bpo]() [3.106449] WARN_ON(!wm_changed) [3.106456] Modules linked in: [3.107267] hid_microsoft hid_generic usbhid rtsx_pci_sdmmc i915_bpo nvidia_drm(POE) nvidia_modeset(POE) nvidia(POE) intel_ips i2c_algo_bit drm_kms_helper syscopyarea psmouse sysfillrect sysimgblt fb _sys_fops drm ahci rtsx_pci libahci i2c_hid hid pinctrl_sunrisepoint video pinctrl_intel fjes [3.109187] CPU: 3 PID: 24 Comm: kworker/3:0 Tainted: P OE 4.4.0-77-generic #98-Ubuntu [3.110085] Hardware name: Dell Inc.

Not related to screen locking, happens less then 4 seconds after clean boot and then randomly. Nothing nvidia related installed on system.

Ok so I traced this to occuring after you install the nvidia driver. Using the intel card or the nouveau drivers the kernel log was clean. It was only after installing nvidia drivers (I tried various versions, from 367 up to 375) that I saw that in the kernel logs. Either way, for me it does not seem to be actually affecting anything. My laptop (Precision 5510) is able to drive the external 4k monitor as well as its normal 4k screen. It's also able to push sound to the external 4k monitor (has built in speakers). So sound is working and so is the resolution. This error, while definitely concerning (and it definitely went away when I upgraded to the 4.8.x kernel), doesn't seem to actually affect me negatively. Additionally, I downgraded back to the original Ubuntu 14.04 based image Dell officially released the Precision 5510 with, to see if they'd custom patched the older kernel or anything, but they hadn't. Same error shows up in the kernel logs on the 14.04 distribution Dell included with the laptop. So they didn't see a need to fix it there either. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1567417 Title: WARN_ON(!wm_changed) skl_update_other_pipe_wm+0x16c/0x180 [i915_bpo] Status in linux package in Ubuntu: Confirmed Bug description: Hi, I'm using a new Skylake Thinkpad T460s with and external monitor connected via Displayport and Ubuntu 16.04 and the latest kernel as of today: Linux test 4.4.0-17-generic #33-Ubuntu SMP Tue Mar 29 17:17:28 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux X will from time to time lock up when the computer is left idle for a long time and both displays (laptop and external) go to sleep and then woken up.

I see this on my Lenovo X1 Carbon (4th gen), a skylake machine. I believe this upstream bug is related: https://bugs.freedesktop.org/show_bug.cgi?id=89055 Comment #62 says: The series that fixes this bug has now been merged to our drm-intel- nightly branch. It should land upstream in kernel 4.8. ** Bug watch added: freedesktop.org Bugzilla #89055 https://bugs.freedesktop.org/show_bug.cgi?id=89055 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1567417 Title: WARN_ON(!wm_changed) skl_update_other_pipe_wm+0x16c/0x180 [i915_bpo] Status in linux package in Ubuntu: Confirmed Bug description: Hi, I'm using a new Skylake Thinkpad T460s with and external monitor connected via Displayport and Ubuntu 16.04 and the latest kernel as of today: Linux test 4.4.0-17-generic #33-Ubuntu SMP Tue Mar 29 17:17:28 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux X will from time to time lock up when the computer is left idle for a long time and both displays (laptop and external) go to sleep and then woken up.
