Created attachment 128608 [details] GPU crash dump saved to /sys/class/drm/card0/error When trying to debug why my desktop will freeze when resuming from a suspend (freshly installed Fedora 25 KDE, i3-4150), I tried following through https://01.org/blogs/rzhang/2015/best-practice-debug-linux-suspend/hibernate-issues and running "echo freeze > /sys/power/state" as root. This suspended my computer, but this time, instead of freezing completely, after a few seconds I could use the computer again, and got this in dmesg output: [ 2413.798896] [drm] GPU HANG: ecode 7:0:0x87d5bef8, in kwin_x11 [1164], reason: Hang on render ring, action: reset [ 2413.798898] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. [ 2413.798899] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel [ 2413.798900] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. [ 2413.798901] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it. [ 2413.798902] [drm] GPU crash dump saved to /sys/class/drm/card0/error [ 2413.798970] drm/i915: Resetting chip after gpu hang I'm attaching the crash dump as described.
Just for information, I still don't know exactly what is making my computer freeze after resume, but `echo 0 > /sys/power/pm_async` does avoid the freezing.

Hello Daniel, Is this bug still valid? Still reproducible in the latest kernel? If so, could you please attach dmesg log with the parameter drm.debug=0xe on grub. Thank you.
Sorry, I cannot reproduce it easily (parents' computer). I will try when I can, with an updated kernel + Fedora, so feel free to close this (I will eventually reopen if the same problem persists).
thanks Daniel for your reply.. and will close as mention but yes open a new bug if the issue exist in a recent configuration.
