Public bug reported:

Since a couple of weeks I'm experiencing a problem with my motherboard.
For some reason the network goes randomly offline and I get a error
messages about AMD-Vi.

[ 6462.248434] AMD-Vi: Event logged [IO_PAGE_FAULT device=04:00.0
domain=0x0019 address=0x0000000000003000 flags=0x0050]

I didn't changed anything except for the internet modem is changed and I
installed updates as I always do. When using google I see there are more
people with this problem exactly the same motherboard, I find this
strange because my pc is almost a year old and I never had this problem.
Could it be a problem in the kernel of *ubuntu 14.04?
