[yocto] Very strange issue where bitbake hangs at do_rootfs

[Andrei Gherzan]

Hello all,

I moved recently on a new arch linux host and everything works fine with
one exception: when I build a custom distribution based on morty with many
packages including kernel-modules (beaglebone), the build system hangs
without any details. I hooked into package_manager.py RPM install and
streamed output from `process = subprocess.Popen(cmd.split(),
stderr=subprocess.STDOUT, stdout=subprocess.PIPE)` and it seems that it
hangs in different places every time. Output example:

If I don't install kernel-modules build succeeds.

Any hints on how to debug this further? I can't seem to find anything
relevant in smart output.
