While this doesn't seem to affect performance or function in any ways, I get these errors when booting 16.04, but only when I have the proprietary Nvidia drivers installed (or possibly the AMD CPU microcode proprietary driver). The error is:
AMD-Vi: Event logged [IO_PAGE_FAULT device=02:00.0 domain=0x0011...
and then continues to show some additional numbers in sequence. See image below.
How can I make these messages go away during boot?
Running Ubuntu 16.04 x64 (Kernel 4.4.0-31-generic), Unity 7.4.0 desktop environment, AMD FX-8150 8x core CPU, 32GB RAM, 2x Nvidia GTX660 graphics cards, Nvidia 361.42 proprietary diver and microcode firmware for AMD CPU's from amd64-microcode proprietary driver.
