            Bug ID: 107950
           Summary: Delayed freeze with DRI_PRIME=1 on Topaz
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: nmset@netcourrier.com

Host : laptop with Kaveri iGPU and Topaz dGPU
kernel : 4.18.4
Xorg : 1.20.1
Mesa : 18.2.0


When running 'DRI_PRIME=1 glmark2', the systems hangs after about 60 seconds.
Must reboot wildly with the power button or magic sysrq, the latter may not
completely power off the laptop.

The iGPU is driven by radeon module, and the dGPU with amdgpu. No module
options, or the following options (amdgpu cik_support=0 si_support=1; radeon
cik_support=1 si_support=0) yield the same result.

I can't say it started with 4.18.4. It's observed on 4.19-rc2/3 also. This
never happened with older kernels.

No such event occurs when using the iGPU.

I cannot bisect, because the last crash badly corrupted the home partition, and
my home directory simply vanished after fsck recreated the ext4 journal. I
could recover from backup fortunately.

May be it's not related to amdgpu, but rather to Xorg, mesa or anything else. I
am reporting it here in case it could be amdgpu in such offloading context.

Regards.

Can you attach the xorg log and dmesg output from your system?

Does updating xf86-video-ati to 18.1.0 or using EXA instead of glamor help by
any chance? Your system is affected by bug 105381.

With EXA, sddm login screen does not show up.

xf86-video-ati 18.1.0 is in testing branch at Arch repositories. Will test when
it'll be available as stable.

(In reply to Michel Dänzer from comment #6)

Tried with xf86-video-ati 18.1.0 :

Same delayed freeze.

I think the host gets overheated. The last line in kernel.log is 

Sep 19 20:44:44 hp2 kernel: [  337.131484] amdgpu: [powerplay] GPU over
temperature range detected on PCIe 0:0.0!

I was monitoring the temperature with 'sensors' command. Last output for amdgpu
sensor was :

amdgpu-pci-0100
Adapter: PCI adapter
vddgfx:       +0.82 V  
fan1:             N/A
temp1:        +190.0°C  (crit = +104000.0°C, hyst = -273.1°C)
power1:        1.04 kW (cap =  30.00 W)

Perhaps powerplay needs some fix ?

Regards.
