Aborted (core dumped) The Processor Service Interface Controller is an internal device. It should only be instantiated by the chip, which takes care of configuring the link required by the ICS object in the case of POWER8. It doesn't make sense for a user to specify it on the command line. Note that the PSI model for POWER8 was added 3 yrs ago but the devices weren't available on the command line because of a bug that was fixed by recent commit 2f35254aa0 ("pnv/psi: Correct the pnv-psi* devices not to be sysbus devices").
