Hi Dan.  After applying version 2 of a7a20d1 I can boot again, but there's
a catch :)

My grub.cfg boot menu entry uses the root=PARTUUID=<guid> syntax, but that
has stopped working.  After a7a20d1(v2) I have to use root=/dev/sda5 or I
get the familiar "can't find block device (foo,bar)" kernel panic.

Any idea what would cause that particular kind of breakage?

Thanks!
