Description Francois 2018-07-26 20:07:20 UTC 
After upgrading to 4.17.10 my screen freezes and is showing white stripes (memory fault?). The issue doesn't show up on 4.17.9 or any lower kernel version.

When the screen freezes, the audio continues to play in the background. A few seconds later however the system just seem to stop completely.

Boot flags: rw radeon.cik_support=0 radeon.dpm=0 amdgpu.cik_support=1 amdgpu.dc=1 amdgpu.dpm=1 scsi_mod.use_blk_mq=1 pcie_aspm=force

I'm using the latest linux-firmware and running Arch Linux.

In the journal I'm unable to find any weird stuff, but I'm happy to provide it if needed.

Thanks.

Please attach your dmesg output.  Can you bisect?

@Alex Deucher just had this issue again and on linux 4.17.9:

Don't hope this is a hardware issue, but for now I don't have any issues on Windows 10.

Thanks.

Does amdgpu.dc=0 on the kernel command line avoid the issue?
Comment 5 Francois 2018-07-27 09:14:29 UTC 
@Michel Dänzer @Alex Deucher Without this flag, the issue remains.
Unfortunately it seems the GPU also starts crashing in Windows, probably the onboard memory died. :/

Thanks for looking at the issue and I'll report back if needed.
