Created attachment 133615 [details] dmesg, showing a boot without iommu=soft Hello amd devs, and whomever it might affect or who is interested. Kernel: 4.12.8 linux-firmware-amd-20170622 xf86-video-amdgpu-1.3.0 CPU: AMD A10-9600P GPU: Radeon R7 (M440 or sth.) After boot when presented with the login screen, the system repeatedly outputs "AMD-Vi: Completion-Wait loop timed out." and most of the time this corrupts the file system while doing this. Booting the kernel with iommu=soft circumvents the problem, but introduces other issues on this machine. I am following this issue for some time now. A have a fairly recent notebook (yes, I know. it's a lot to ask for support on too recent hardware). But i see hope, as there already has been succesfull patching by the amd crew! I found a bugreport on launchpad [1] (strange enough they posted it there), which led to a patch on freedesktop [2], and i happily got it to work with 4.11. System was bootable without the iommu=soft command. With linux now advancing to 4.12, the patch is not applyable anymore, so here i am now, reporting the issue again, in the hope to get new info and a tiny bit of help/advice. Thanks in advance.
