However when setting: debug.acpi.layer="ACPI_ALL_DRIVERS" debug.acpi.level="ACPI_LV_ALL" the system hangs at the Entropy harvesting line (I know those debug settings are too much for debugging Cx support). It also hung when I booted into single-user mode and tried to list the debug.acpi sysctls. Although the system doesn't respond to keypresses, the system isn't totally locked up: pressing the power button a couple of times triggers the message that the system's not ready to switch into S5 mode. -- Bruce Cran
