Bug#810471: libdrm2: [drm] stuck on render ring

[Andreas Berger <andreas.berger.01@gmail.com>]

Package: libdrm2
Version: 2.4.58-2
Followup-For: Bug #810471

Dear Maintainer,

i'm getting the same error message on debian stable upon resume from suspend to RAM. it causes kwin to crash and restart, and dmesg reads:

[12932.309403] [drm] stuck on render ring
[12932.310451] [drm] GPU HANG: ecode 0:0x00dff888, in Xorg [4535], reason: Ring hung, action: reset
[12934.304711] [drm] Enabling RC6 states: RC6 on, RC6p off, RC6pp off

i first experienced this a few days ago, and since then it has happened on about 80% of the times i resumed from suspend.
the odd thing is that, for all i know, i hadn't changed anything about the system when this started, except for using wifi.
