Intel Vt-d document addresses RMRR, but not that clearly. Check BIOS setup, no link share, for example, a nic detect by linux kernel, it was shared by BIOS for IPMI. If change BIOS setup don't solve your problem, contact platform vendor update nic firmware, a server made by HP, check HP's website for firmware. > >====== >BOOT_IMAGE=/boot/vmlinuz-3.10.0-957.el7.pw.1.x86_64 root=/dev/sda3 >intel_iommu=on > > >Can anybody suggest how to work around the issue ? > >Thanks, >Regards, >Venu
