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 If you get something else, please check this post. https://ubuntuforums.org/showthread.php?t=2254677 Thanks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1610622 Title: AMD-Vi: Event logged [IO_PAGE_FAULT device=02:00.0 domain=0x000f address=0x00000000bec09880 flags=0x0010] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1610622/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
