flash-kernel will append a dtb by default, which I think will take
precedence over anything you provide via the bootloader. When you say
"no dtb" do you just mean "didn't give one in the bootloader"? Do your
kernels have one appended? IIRC dreamplug never had board-file support
so a dtb must be coming from somewhere.
The uImage header is 64 bytes so the uImage should either be
sizeof(vmlinuz)+64 or sizeof(vmlinuz)+sizeof(dtb)+64.
OOI what happens if you boot the Jessie kernel without a
bootloader-provided dtb?

This is interesting, on my system I rely on the appended DTB (which
flash-kernel does automatically) rather than loading anything by hand.

IIRC this is mostly the factory supplied env (although I'm running
current Debian's u-boot, version 2014.10-rc3+dfsg1-1).
The default env built into Debian's u-boot (i.e. what you get out of
"env default -a") differs from what either of us have AFAICT. It loads a
kernel from FAT and doesn't load an initrd or dtb at all.

No root=?
Do you have any local overrides to the flash-kernel db? In particular to
the Bootloader-Sets-Incorrect-Root setting? (Previously called
Bootloader-Sets-Root).
This isn't your current issue, since it's not seeing any device so the
root= would be useless, but it would perhaps be the next issue you would
hit...

This doesn't appear to have actually used your initrd, despite you
having loaded one above, in particular there is no "Unpacking
initramfs..." message and none of the expected logging from the
initramfs.
I'm not sure why this should be. Seeing your u-boot bootcmd might be
helpful/informative.
I've pasted my dmesg (without the sda errors) below, FWIW. They look
pretty much the same up to the point where yours panics and mine loads
the initramfs.
