i am getting "GPU HANG: ecode 9:0:0x85ad939e, in Xorg , reason: Hang on rcs0" error message in kernel log when i stream video using Gstreamr libs. attached GPU crash dump. any help is appreciated.
Linux version 4.15.0-29-generic
DMC firmware i915/kbl_dmc_ver1_01.bin (v1.1)
Xorg server: 1.19.6
A real GPU hang:
looks more like pixel data than an instruction
If your userspace stack is as old as the kernel; both require updates :)
Thanks for the reply. i will try to upgrade both the stack and the kernel and share the results. but i would like to know what is the root cause of this issue. is the problem occurs because of known bug in user stack or kernel driver? is there a way to trace what exactly gone wrong during the crash ?

Unless we bisect the issue we can't know what is causing this issue. Anyway we always recommended to upgrade kernel to latest. Please try to reproduce with (https://cgit.freedesktop.org/drm-tip).
