yesterday I got rid of the AMD-Vi error messages by editing the bootflags with grub and adding iommv=soft, but stretch still locked up after a message something like tpm_crb MSFT0101:00 can't request region for resource [mem 0xddd21000 - 0xddd24fff. so this morning I used the rescue mode of the netinst disk to dist-upgrade to buster. I'm blogging this right now from rescue mode... about to reboot and see if it works.
