OK, thanks for checking. I'm running the Linux-libre 4.18 kernel built from
source with powernv_defconfig -- I should have mentioned that in the
initial report, sorry.  I'll try the debugging steps you've suggested when
I get back to my system, and narrow down what the relevant options are.
Everything else on my system is stock Debian stretch packages.
