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]
Actually, you helped more than you think. :-)
So I did a little reading about the IOMMU issue and the problem is that
IOMMU itself is not the problem. It just shows the real problem (I
think this is not new news, really.) Anyway, the problem appears to be
the xhci_hcd device driver that I
I did that. Will that affect new boot images as well? i.e. the ones I
get after installing updates.

Title:
IO_PAGE_FAULT
Status
With the risk of sounding foolish, how do you do that?
I have an HP Pavilion HE desktop and I looked around the BIOS setup
options, but couldn't find an obvious one for that. Searching the HP
support site returned no info about IOMMU.
Thanks much for your help.

Can somebody look at this problem? It seems that the USB 3.0 support is
at issue here. Device 04:00.0 is the USB 3.0 controller, according to
lspci:
04:00.0 USB controller [0c03]: VIA Technologies, Inc. VL80x xHCI USB 3.0
Controller [1106:3432] (rev 03)
I saw this in kernel version 3.13.0.59
I am seeing the same issue starting w/kernel version 3.13.0.59.
