[systemd-devel] Boot error on PowerPC

[Alessio Igor Bogani]

Dear systemd developers and maintainers,

I incurred in the following error during the boot on a PowerPC based
on MPC7410 cpu using systemd v230:

systemd[1]: Failed to insert module 'kdbus': Function not implemented

Please consider that:
1) It works on an ARM, a x86 and a (recent) PowerPC systems
2) It also doesn't work on an other PowerPC which uses the same
instruction set (ppc7400)
3) The coredump isn't generated and debug shell doesn't come up
4) I have already disabled LTO/gold

Could you suggest me how track down (or workaround) the problem, please?

Thank you very much!

Ciao,
Alessio
