Hello!
The following happens with Linux 4.4.1 during boot on an MSI A78M-E35
board. Additionally, I attached the complete dmesg.
I was working on upstreaming changes to the AMD IOMMU Perf to fix some
of the similar issue I saw on a different platform. Would you please
check to see if this patch series would fix this?

This patchset seems to fix the problem.
[ 1.264639] AMD-Vi: IOMMU performance counters supported
But there seems to be a problem with the location of
perf_event_amd_iommu.h in the patch - I had to fix the complete
perf_event_amd_iommu.h related patches to get them applied to 4.4. and
finally compiled.
Thanks,
Andreas
Ok, I'll clean up and resend this patch series. Thanks for testing.
Thanks,
Suravee
