Hello, I tested upcoming 4.17 kernel preview and I had regression in i915 similar to https://lists.freedesktop.org/archives/dri-devel/2017-November/159207.html
I reported issue here: https://bugzilla.kernel.org/show_bug.cgi?id=199315 Manjaro Linux x86_64 [fademind@manjaro ~]$ pacman -Q|grep linux417 linux417 4.17.r180407.f605ba9-1 linux417-bbswitch 0.8-0.2 linux417-nvidia 1:390.48-0.2 linux417-r8168 8.045.08-0.2 [fademind@manjaro ~]$ 00:02.0 VGA compatible controller [0300]: Intel Corporation 3rd Gen Core processor Graphics Controller [8086:0166] (rev 09) Subsystem: ASUSTeK Computer Inc. 3rd Gen Core processor Graphics Controller [1043:1447] Kernel driver in use: i915 Kernel modules: i915 Coredump CUT PART from dmesg ``` [ 0.660493] hctosys: unable to open rtc device (rtc0) [ 0.664071] Freeing unused kernel memory: 1456K [ 0.664072] Write protecting the kernel read-only data: 16384k [ 0.665145] Freeing unused kernel memory: 2016K [ 0.668612] Freeing unused kernel memory: 760K [ 0.710475] Linux agpgart interface v0.103 [ 0.751937] checking generic (d0000000 300000) vs hw (d0000000 10000000) [ 0.751939] fb: switching to inteldrmfb from EFI VGA [ 0.751955] Console: switching to colour dummy device 80x25 [ 0.752030] [drm] Replacing VGA console driver [ 0.755096] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
