I am running Parabola on a Libreboot T400 that I purchased from Ministry of Freedom. I have not made any changes to Libreboot.
Every time I boot into my Parabola installation, I see this message: "DMAR: Failed to map dmar2". I booted into Parabola's live CD just to see what would happen, and the same message scrolls by during the boot process. Once Parabola is fully booted and I'm at the desktop (mine or live CD's), everything seems to be working fine. Here are the relevant lines from dmesg: http://pastebin.com/Fw7NH6tn What does this DMAR failure mean? Is it fixable? If not, is there a way to make the error stop showing up during boot? I read somewhere that adding iommu=soft to the kernel boot parameters makes the error go away, but that didn't have any effect. Thanks, Bruno
