I "fixed" this with https://github.com/mjg59/grub-fedora/commit/21fcd6d79b7601e4b20ad70c5408adff2dabbc1d - doing the same in the kernel EFI stub would probably be the best way to handle it. This way you're guaranteed to stop DMA before the kernel reclaims boot services memory, which guarantees you won't have any corruption. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
