Hello List,

I updated my server to CentOS 6.5. When i boot the system with the new
kernel: 2.6.32-431.el6.x86_64 I get repeating the following message:

dmar: DRHD: handling fault status reg 3
dmar: DMAR:[DMA Read] Request device [00:02.0] fault addr 1fc00000
DMAR:[fault reason 06] PTE Read access is not set

I use a Intel Core i5-3550 CPU  with vt-d enabled to use a DVB-S Card
inside a Windows VM (kvm).

With the old 6.4 Kernel all works (2.6.32-358.23.2.el6.x86_64)

lscpi shows this:
[...]
00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd
Gen Core processor Graphics Controller (rev 09)
[...]

Is this a problem with the intel driver or anything else?

Regards,
Sebastian Marten
