Oh yeah, that, too. Mine is the last comment on
https://bbs.archlinux.org/viewtopic.php?id=186503. I had to enable IOMMU in
bios, then disable it in kernel using iommu=soft.

Yes, the BIOS eats up your flash drive. Maybe it only knows FAT32 or NTFS
or something. Just don't have it do any reading or writing to a drive with
anything important on it. It also does this to hard drives, so stay away
from screenshots, etc.

I'm happy you got it worked out!
