syntaxx Posted October 29, 2015 Share Posted October 29, 2015 What is this? I am getting this in my syslog and dmesg. 00:1d.0 is my usb passthrough. I also noticed that this one will slow down my transfer rate. 00:1d.0 USB controller: Intel Corporation 7 Series/C210 Series Chipset Family USB Enhanced Host Controller #1 (rev 04) dmar: DRHD: handling fault status reg 3 dmar: DMAR:[DMA Read] Request device [00:1d.0] fault addr ef000 DMAR:[fault reason 06] PTE Read access is not set kvm: zapping shadow pages for mmio generation wraparound Thanks Quote Link to comment
RobJ Posted October 29, 2015 Share Posted October 29, 2015 I believe I've seen that before, with the same or similar chipset family. Check for a newer BIOS. And try toggling various BIOS switches, such as USB, virtualization, other? Quote Link to comment
syntaxx Posted October 29, 2015 Author Share Posted October 29, 2015 I have all the virtualization set to on. I will try to fiddle with the bios this only happened when i switched to unraid 6. Also I see in the web about intel_iommu=pt instead of on. not sure if it works on unraid. Quote Link to comment
