Hi,
maybe the below is of interest
I managed to capture some info after a hard-lock of the gpu (rx480):
on TTY1 (I believe) I get the following message:
amdgpu 0000:01:00.1: Invalid PCI ROM header signature: expecting 0xaa55, got
0xffff
in dmesg I found:
[29231.774334] Watchdog[2763]: segfault at 0 ip 00000000f4732ce7 sp
00000000ad79ea20 error 6 in libcef.so[f1451000+419c000]
[33015.898836] Watchdog[3099]: segfault at 0 ip 00000000f467ace7 sp
00000000ad6e6a20 error 6 in libcef.so[f1399000+419c000]
The GPU was hooked into a TV via HDMI (secondary)
The primary monitor was attached but switched off via gnome3 settings
All the above happened play Tomb Rider
Similar behaviour with Shadow of Mordor
I am on latest Antergos:
4.8.8-2-ARCH #1 SMP PREEMPT
X.Org X Server 1.18.4
cat /etc/X11/xorg.conf.d/20-amdgpu.conf
Section "Device"
Identifier "AMD"
Driver "amdgpu"
Option "DRI" "3"
EndSection
I hope the above can be helpful
Cheers
M.
