Kernel config: PANHARNESS = X86_64_GENERIC + "device panasim" (line 56 of the
  generic config: "options INVARIANTS" -- INVARIANTS kernel, confirmed live by
  KKASSERT assertion panics and by kfree(NULL) INVARIANTS panic during fix
  iteration).

Hardware note: guest has no Panasonic MAT0019 ACPI device; the rig supplies
  the firmware side (probe/notify/SINF/HINF/SSET) at the exact API boundary
  the driver consumes. hw.acpi.power_profile_state machine state: PERFORMANCE
