I bisected it up to ae9304c9d31117 ("Adding selftest testdata
dynamically into live tree"). For a while, my kernels are compiled w/
OF_SELFTEST and it works w/o issue. After that commit, boot hangs as

It would be interesting to have a feedback of a kernel with an appended dtb
and OF_SELFTEST enabled to a different platform (ie non mvebu). Then we
will know if it something related to mvebu or to the device tree support.

I will try to see if I can do this.

I can test that on a kirkwood (6282) this evening.

FWIW, the problem does not only show up on Armada 370 but also on
kirwood. I just tested it on a ReadyNAS Duo v2. I do not have any
other non-mvebu platform at hand ATM. I'll try and see if I can
find some ARM board to boot a recent kernel tomorrow.

Ok, I just built an u-boot and two 3.17.1 kernels for versatile express,
which I then loaded via qemu. The result is the same as for mvebu, i.e.
w/o OF_SELFTEST the first kernel just boots as expected and the second
kernel compiled w/ OF_SELFTEST hangs. Both kernels are built w/ appended
dtb support.

Cheers,
