[Bug 1447053] Re: IO_PAGE_FAULT


I meant kernel packages and not boot images, sorry.  You answered my
question, thanks so much.

After setting iommu=soft, I noticed that the kern.log file was getting quite huge.  I noticed there are a large number (over 31 millions) of errors like this:
Dec 13 08:25:01 HP kernel: [25953.936777] hub 10-1:1.0: hub_port_status failed (err = -22)
Dec 13 08:25:01 HP kernel: [25953.936781] hub 10-1:1.0: hub_port_status failed (err = -22)
Dec 13 08:25:01 HP kernel: [25953.936785] hub 10-1:1.0: hub_port_status failed (err = -22)
Dec 13 08:25:01 HP kernel: [25953.936788] hub 10-1:1.0: hub_port_status failed (err = -22)
Dec 13 08:25:01 HP kernel: [25953.936791] hub 10-1:1.0: activate --> -22

I verified the status of the USB hub and all ports have a status of
"active".  The ep_81 status says disable.  I think I'll have to dig more
into this and understand what's the significance of those entries in

Thanks much.

Bug description:
  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?
