AMD-Vi: Event logged Error

I have recently started getting this message in the logs:

AMD-Vi: Event logged [IO_PAGE_FAULT device=01:00.0 domain=0x0017 address=0x0000000000001000 flags=0x0000]

From searching it appears that this is a known bug and that the workaround is to add iommu=pt to the linux command line. However if I do this then my USB 3.0 ports are no longer recognised:

kernel: hub 3-0:1.0: Cannot enable port 1.  Maybe the USB cable is bad? (added error message)

Can someone help me with this please?

Re: AMD-Vi: Event logged Error

You do have IOMMU enabled in the BIOS, right? (Otherwhise USB2 and network would be broken I guess)
So, do you have any disks or other drives attached to the Marvell SATA controller?

Re: AMD-Vi: Event logged Error

Yes, IOMMU is enabled in the bios

Not sure what is connected to the SATA controller, but I am pretty sure there are several devices attached.

The USB cable error message has disappeared now.

So I am none the wiser. but everything seems to be back to normal

Thanks for the response

Re: AMD-Vi: Event logged Error

I am having the same issue, also with the same Phenon CPU but with an ASUS motherboard, and a GeForce 9400 GT. For a couple of months my dmesg and error logs are full with "AMD-Vi: Event logged [IO_PAGE_FAULT device=01:00.0 domain=0x0016 address=0x0000000000001000 flags=0x0000]", and if I disable iommu or pass "amd_iommu=off" to the kernel, my network and USB ports don't work. Anyone has been able to fix this?

Re: AMD-Vi: Event logged Error

You did try "iommu=pt" didn't you?

Re: AMD-Vi: Event logged Error

You can work around this by disabling the hw iommu. To do so, add iommu=soft to the kernel commandline and make sure you have no other iommu options set. A lot of mobos seem to have broken AMD-Vi implementations.
