By the way,when I removed the "intel_iommu=on" from /etc/grub.conf,no DMAR related errors occur It's a strange thing,other three Dell R710 servers with the same bios version v. 6.3.0, same kernel 2.6.32-279.14.1 on RHEL6u3(Centos 6u3) ,but these errors don't appear on these tree servers Anyone have any idea for this ? thanks -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
