[19265.715634] [drm] stuck on render ring
[19265.716066] [drm] GPU HANG: ecode 7:0:0x85fffffc, in chromium-browse [3924], reason: Ring hung, action: reset
[19265.716067] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[19265.716068] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[19265.716068] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[19265.716069] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

[19265.716069] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

But first please install a more recent kernel than v4.4.

Comment 2 Gunter Ohrner 2017-03-06 21:29:41 UTC

Upgraded to Ubuntu mainline build 4.10.1 - let's see what happens...

Gunter, do you have any update following this upgrade?

Not yet, so far it's working fine - but also with Kernel 4.4 it was no frequent problem, so I'll have to monitor it for a while.

Comment 5 William Deans 2017-03-29 18:47:56 UTC

In dmesg I see:
GPU HANG: ecode 7:0:0x85fffffc, in chrome [17156], reason: Ring hung, action: reset

uname -a
========================
Linux deansw530 4.4.0-66-generic #87-Ubuntu SMP Fri Mar 3 15:29:05 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

/sys/class/drm/card0/error
====================
$ cat /sys/class/drm/card0/error:
cat: '/sys/class/drm/card0/error:': No such file or directory


I will upgrade my kernel day after tomorrow after some long running processes complete and see if it still happens.

Comment 6 Shanaa@~ 2017-04-09 22:32:01 UTC

I'm having the same issue.
on Intel i7-5500U with intel hd 5500
mesa-17.0.3
xorg-1.19.2
using modesetting driver.

Funny enough, this problem doesn't occur when using wayland via sway wm,
but occurs every time on xorg.

dmesg:

Comment 7 Elizabeth 2017-06-27 19:46:56 UTC

Hello everybody,
Is this hang still reproducible with the last kernel update? If so, please attach the error log /sys/class/drm/card0/error. If you have any problem with that please clean with ‘echo 0 >/sys/class/drm/card0/error’ and try again. Thank you.

Comment 8 Gunter Ohrner 2017-06-28 06:19:42 UTC

For me, it only occured very rarely with Ubuntu's kernel 4.4.0-something and not at all so far with a 4.10/4.11 series kernel. So I cannot reproduce and I'm out.

Thank you for the update Gunter. Since you are the original owner of this bug, I'm going to close it as fixed. For Shanaa and William, if the problem persist, please open a new bug with HW and SW information and the logs attached. Thank you.
