:[Firmware Warn]: Your BIOS is broken; DMAR reported at address fed90000 returns all ones!
I googled "Your BIOS is broken; DMAR reported at address fed90000 returns all ones!" and got some related results.
My search fu was weak. Very weak.
this bug report (on FC12) says... "yes, your bios is broken, but its not a bug, we worked around it" https://bugzilla.redhat.com/show_bug.cgi?id=896652
Well since Centos 6 is about equiv to F12, I guess I can 'live' with claim. But then, how to stop the constant error reporting?
on a similar/identical bug with Fedora FC17, someone suggested booting with iommu=off to work around this.
Where do I add this?
On the kernel line in grub.conf
