Package: linux-image-4.11.0-0.bpo.1-marvell Version: 4.11.6-1~bpo9+1: armel
I had Debian Stretch installed on my QNAP TS-219P II and already upgraded to the backports kernel linux-image-4.9.0-0.bpo.3-marvell (4.9.30-2+deb9u2~bpo8+1: armel). Upgrading that to the package specified above yielded a no-boot situation.

OK OK Starting kernel ... Uncompressing Linux... done, booting the kernel. That's it, no further output, no boot. The kernel seems to die early on. I've observed such early failures on another platform when a "bad" device tree binary was flashed. Is it possible that kernel 4.11 requires a changed dtb, and that was not correctly upgraded?
