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?
