19 So you have a /boot and a /boot/efi partition. Hmm.
20
21 My /boot is just a sub-directory on /dev/md3 ... might make a difference
22 at boot-time.

24 I had EFI stuff working already but with both /root and /boot on plain
25 partitions on the SSD, without any underlying raid.

27 (this SSD started getting flaky lately, leading to all this)
28
29 I might try setting up a separate /boot now, GPT allows many partitions
30 anyway ;-)
