Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.8 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I also had a problem with a Gigabyte motherboard model GA-990FXA-UD5 R5, disabling the IOMMU solve the problem but it disables some USB ports.

I've solved this by adding "iommu=pt" at /etc/default/grub, find the line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

and add:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash iommu=pt"

Save it, run sudo update-grub and reboot. After that the event will be gone and you should see somethign like this

[ 1.536343] AMD-Vi: Found IOMMU at 0000:00:00.2 cap 0x40
[ 1.536344] AMD-Vi: Interrupt remapping enabled
[ 1.536356] pci 0000:00:00.2: irq 72 for MSI/MSI-X
[ 1.536490] AMD-Vi: Initialized for Passthrough Mode
