Yeah, I agree. In the later dmesgs, though, it seems to be enabled.
Those don't show any failure.
no they don't. basically it just says your bios hasn't configured enough
IOMMU space, so the kernel is going to do it anyway. it's really just a
warning or an fyi rather than an error. i may have chosen the word
poorly ;-)
in short Sean, this isn't a big deal. you only really need to change
this if you want to remove a warning from your dmesg output.
