Hi,

ARMv7 images are broken.

On boot, with latest build (kernel 4.4.0-3-default) I get the following error: "Initramfs unpacking failed: write error". Full kernel log (for beaglebone black): ******************************************************** Starting kernel ...

Note that there is no early message (except warning on console, for which I will send a JeOS SR).

Any idea what is wrong? Looks like the initrd is too big (again). Please try to set the rootfstype to ramfs in the kernel command line to verify.

It did the trick indeed!

I guess we really need to come up with a good way around this whole mess. I like the squashfs-in-initramfs approach the best so far...

Why kernel does not handle it right without 'rootfstype=ramfs'? Could we tweak kernel config so that it works with large initramfs? squashfs-in-initramfs approach would need some kiwi work, I guess? Guillaume

Any kernel config update related to initramfs?
