chv_set_memory_dvfs: *ERROR* timed out waiting for Punit DDR DVFS request I got a very similar error: [drm: valleyview_update_wm [i915_bpol]] *ERROR* timed out waiting for Punit DDR DVFS request uname -a Linux 3.19.0-26-generic #28-Ubuntu SMP x86_64 Happens also on Debian Testing. System: Intel NUC5CPYH CPU: Celeron N3050 GPU: Intel HD Graphics (Device ID: 22B1) (In reply to samuel.vonstachelski from comment #2) > I got a very similar error: > > [drm: valleyview_update_wm [i915_bpol]] *ERROR* timed out waiting for Punit > DDR DVFS request > > uname -a > Linux 3.19.0-26-generic #28-Ubuntu SMP x86_64 > > Happens also on Debian Testing. > System: Intel NUC5CPYH > CPU: Celeron N3050 > GPU: Intel HD Graphics (Device ID: 22B1) We have the same error on the exact same machine. Did you find any solutions yet? Did you experience any fatal crashes caused by this bug? Thanks Sounds like the Punit is unhappy. You should check for a BIOS update first. Hmm. And the one comment with a kernel version listed is using some Ubuntu frankenkernel. Can anyone reproduce the problems with upstream 4.1 (first one to have official CHV support) or drm-intel-nightly? Mine was on -nightly on the braswell nuc. It is also apparent on every kernel since circa 4.0 that I have successfully booted on that machine. (In reply to Chris Wilson from comment #6) > It is also apparent on every kernel since circa 4.0 that I have successfully > booted on that machine. Does it still happen with current nightly? The way we did it with 4.1 was to just keep disabling dvfs every time, but with the current code we shouldn't ask the Punit to do anything if the current state is already correct, so that might make the Punit happier.

Thnkas for all Created attachment 122672 [details] GPU crash dump Hi guys I have the same issue here, plus I got a GPU Hang. Hopefully I saved the dump so I'm more than happy to share It with you guys. This system is quite unstable here. First because of a kernel bug I have to set the status to C1 on this machine, if not the system will hang after few minutes https://bugzilla.kernel.org/show_bug.cgi?id=109051 now the gpu is misbehaving showing corrupted graphics and spontaneous failures like these reported in this bug. I hope that the info that I'm attaching could help you. Comment on attachment 122672 [details]
GPU crash dump
GPU hang dump + system information
Created attachment 122677 [details] GPU crash dump since yesterday I did some changes to the system to discard reporting an error that It is already fixed. First of all I updated the system with the latest bios from Asrock (released just few days ago) 1.70 http://www.asrock.com/nettop/Intel/Beebox%20Series/?Model=N3000-NUC&cat=Download&os=BIOS Second, I updated all the X.org packages to the latest version using the latest versions available: xf86-video-intel-2.99.917-162.1.x86_64 libdrm_intel1-2.4.67-189.1.x86_64 intel-gpu-tools-1.14-54.1.x86_64 ucode-intel-20150121-3.3.x86_64 vaapi-intel-driver-1.6.2-37.3.x86_64 repo URL http://download.opensuse.org/repositories/X11:/XOrg/openSUSE_Leap_42.1/ With this new setup It is harder to reproduce, but after 2 hours of intensive use I got It reproduced. Attached file contains dump + system information. Comment on attachment 122677 [details]

Please don't mix up different issues in one bug. A new bug should be filed for the GPU hangs. Marking this as fixed again. Sorry, I got distracted because I got the cpu hang right after the issue that we are discussing here, hence I thought that It was somehow related. Thanks for confirming that It is not related, I will reorganize this bug and open a new one for the cpu hang. |
