Thanks for the suggestion. Did not complete boot however, got a
slightly different call trace, but still no go. As that trace crossed
_prepare_cpus I tried adding nosmp, but we still crash in
acpi_init->acpi_scan_init->acpi_bus_scan->acpi_bus_attach

Any other suggestion? lspci normal and verbose follow...
