Based on this:

[custom kernel]
/dev/sdb: PTUUID="25169f0a-30ad-47e5-81a9-d74ae8286776" PTTYPE="gpt"

[standard kernel]
/dev/sda: PTUUID="25169f0a-30ad-47e5-81a9-d74ae8286776" PTTYPE="gpt"
/dev/sda1: PARTUUID="1e4484e1-1499-4f9a-bd2f-e0f4d61e9920"
/dev/sda2: UUID="48537739-1f62-4c12-8bf1-9d662d8cc74f" TYPE="crypto_LUKS" PARTLABEL="dk" PARTUUID="6b5c5648-1b4b-4be5-83d7-7c47eb8b53a6"
/dev/sda3: UUID="bf028ceb-d1fa-4f62-b41f-d9d44adbe65a" TYPE="ext4" PARTUUID="5970fa70-34fa-4eca-aaf7-f085c9b55a27"

I would guess that you didn't enable CONFIG_EFI_PARTITION and thus the
kernel can't decode the partition table.

That shouldn't be a problem, as it will be retried at intervals (as
you've seen).

It is your kernel configuration.

Ben.
