Bug#870185: Acknowledgement (FATAL: kernel 4.11.0-0.bpo.1-marvell does not boot on QNAP TS-219P II)
I just noticed the line
[ 0.267305] Unpacking initramfs...
[ 0.270704] Initramfs unpacking failed: junk in compressed archive
[ 0.304492] Freeing initrd memory: 9216K
in the output above, so I tried using the same initrd.img from flash with kernel 4.9 and kernel 4.11:

So it turns out that kernel 4.9 is able to unpack the initrd.img for kernel 4.11, while kernel 4.11 can NOT unpack the same initrd.img.
Has the compression/format of initrd.img changed between kernels 4.9 and 4.11? Do the initramfs-tools need to be updated to create valid initrd.imgs for kernel 4.11? Maybe there was "only" a dependency missing when upgrading to kernel 4.11?
How would I convert the "bad" initrd.img to the proper format that kernel 4.11 can decompress...?
