dmesg, showing a boot without iommu=3Dsoft

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 outp=
uts
"AMD-Vi: Completion-Wait loop timed out." and most of the time th=
is corrupts
the file system while doing this.
Booting the kernel with iommu=3Dsoft 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 cr=
ew!


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=3Dsoft command.

With linux now advancing to 4.12, the patch is not applyable anymore, so he=
re i
am now, reporting the issue again, in the hope to get new info and a tiny b=
it
of help/advice.


Thanks in advance.
