This bug looks similar to https://bugs.freedesktop.org/show_bug.cgi?id=111122
Could you try the various workarounds proposed there and see if it helps:
- adding the iommu=pt kernel boot parameter (see
https://wiki.archlinux.org/index.php/kernel_parameters#GRUB)
- or using the AMD_DEBUG=nodcc environment variable (for instance, try
adding a new line with "AMD_DEBUG=nodcc" in the /etc/environment file and reboot)
- or updating Mesa to the latest version
So adding "iommu=pt" to the kernel parameter dose help, thanks a lot!
