System log leading up to hard crash
Description:
Periodically my system will begin to slow down dramatically (the mouse cursor
hitches as I try to move it) and I am unable to interact with anything on the
screen. Eventually the mouse cursor disappears altogether. Trying to switch
to a tty I do get prompted to login, but after entering my credentials nothing
happens. It appears to be a hard lockup. The only solution is to manually
power down my machine and reboot.
This probably happens one or two times a day, normally after starting a new
application.
Hardware:
Dell XPS 15 9575 2 in 1 (Kaby Lake G)
Versions:
Kernel 4.18-rc7
Mesa 18.1.5
Xorg 1.19.6
uCode for Vega M from Linux Firmware git (master) which includes the latest
18.20 uCode from AMD that was recently merged into Linux Firmware
I do have the two sinks available (one for the Intel iGPU and one for the AMD
Vega M), running:
xrandr --listproviders
Lists the following:
Providers: number : 2
Provider 0: id: 0x6f cap: 0x9, Source Output, Sink Offload crtcs: 3 outputs: 7
associated providers: 1 name:modesetting
Provider 1: id: 0x45 cap: 0x6, Sink Output, Source Offload crtcs: 6 outputs: 0
associated providers: 1 name:Unknown AMD Radeon GPU @ pci:0000:01:00.0
And running:
env DRI_PRIME=1 glxinfo | grep "OpenGL renderer"
Lists:
OpenGL renderer string: AMD VEGAM (DRM 3.26.0, 4.18.0-041800rc7-generic, LLVM
6.0.0)
So the Vega M is active and available in my system.
I noticed that this problem started happening after the release of kernel
4.18-rc6 and continues with 4.18-rc7. I've been using 4.18 since rc1 without
issue. This entry in the changelog caught my eye:
Leo Liu (1):
drm/amdgpu: Make sure IB tests flushed after IP resume
Not sure if this is at all related, but the reason I bring this up is because
the errors I see in my logs everytime I encounter this problem are:
kernel: amdgpu 0000:01:00.0: GPU pci config reset
kernel: [drm:amdgpu_device_ip_suspend [amdgpu]] *ERROR* suspend of IP block
<uvd_v6_0> failed -12
Please note that so far I have only encountered this problem when launching
applications that use my Intel iGPU (i.e. I am not setting DRI_PRIME=1).
I've attached my entire log to provide more context.
Thanks!</pre>
