Created attachment 124559 [details] dmesg Hi! I am running the linux mainline (4.7.0rc3 as of this writing) on a thinkpad x260 connected to a docking station/port replicator with two displayport monitors attached and, except for the good ol' WARN_ON(!wm_changed) warnings I am experiencing occasional freezes. To me they seem to happen at random. my dmesg is attached. lspci: 00:00.0 Host bridge: Intel Corporation Skylake Host Bridge/DRAM Registers (rev 08) Subsystem: Lenovo Device 504a Control: I/O- Mem+

I forgot to type in that it does not seem to happen when I don't have any external monitors connected.

(Sorry, that comment turned out less helpful than I thought it would.)
Please try https://patchwork.freedesktop.org/patch/93561/
I am compiling the kernel with the patch applied right now and will report back. It might take some time considering I don't know how to reproduce it and sometimes it doesn't happen for days. Although sometimes one or both external monitors goes black for a short while before it comes back. Could that be related or should I create a new issue for that? I don't have a log right now for it but if you want I could create a new issue the next time it happens.
this fails to compile with: drivers/gpu/drm/i915/intel_fbdev.c: In function ‘intel_fbdev_restore_mode’: drivers/gpu/drm/i915/intel_fbdev.c:827:12: error: ‘struct intel_fbdev’ has no member named ‘cookie’ if (ifbdev->cookie) { ^~ drivers/gpu/drm/i915/intel_fbdev.c:828:34: error: ‘struct intel_fbdev’ has no member named ‘cookie’ async_synchronize_cookie(ifbdev->cookie + 1); ^~ drivers/gpu/drm/i915/intel_fbdev.c:829:9: error: ‘struct intel_fbdev’ has no member named ‘cookie’ ifbdev->cookie = 0;
Apologies, patch 44/44, but fortunately it should only depend upon https://patchwork.freedesktop.org/patch/93560/
