Hi,

I tested smokey with qemu-amd64, qemu-arm and qemu-arm64 from xenomai-images 
with the dh_strip patch active against master and had following results:

qemu-amd64 - smokey run
qemu-arm and qemu-arm64 stall with the attached output.

Kind regards,

Which kernel version(s) are showing this issue on arm[64]?



On arm:
Linux demo 4.14.85+ #1 SMP Tue Aug 13 16:57:48 UTC 2019 armv7l GNU/Linux


We need ipipe-core-4.14.96-arm-6 at least.


On arm64:
Linux demo 4.14.78+ #1 SMP PREEMPT Wed Aug 14 07:11:31 UTC 2019 aarch64 
GNU/Linux



Yeah, and we still need patches for arm64 in fact, analogously to 
https://gitlab.denx.de/Xenomai/ipipe-arm/commit/d36ce64b54b9f763fc337e70ebb313fba63f944a.
