When using kernel 4.15.0-12 the system does not power off but instead reboots. Both halt -p from the command line and menu action leads to reboot. Booting with previous kernel 4.15.0-10 resolves the issue, system turns off power as expected. I am not attaching any logs because I cannot see anything unusual there, kern.log entries from 4.15.0-10 and 4.15.0-12 seems to be identical (in fact, there is only one entry there "msr: Direct access to MSR 1b0").
