So we could check to see if Linux has made any changes to their imported sources, and how they handle the power-down. From what you have told us, it appears that your machine is failing at some stage in calling three functions: AcpiEnterSleepStatePrep(ACPI_STATE_S5); ACPI_DISABLE_IRQS(); AcpiEnterSleepState(ACPI_STATE_S5); We could specifically compare the handling of these three functions in FreeBSD and Linux, if you know that your computer works under Linux. If you want to enable debugging as I mentioned in a previous message (the one where you compile kernel and modules with ACPI_DEBUG, which can give us a lot more information than even hw.acpi.verbose=1), we can learn more about exactly where the problem occurs. There are a couple of other things you can try: if you think that a certain piece of hardware is connected with the problem (again, we would know more if debugging was enabled), you can try: 1) physically removing the hardware; 2) going into the BIOS setup and disabling the hardware, if possible; or 3) disabling the ACPI subsystem that handles that hardware via /boot/loader.conf Also, have you tried FreeBSD 8 to see if that works for you? In the meantime, you can safely power down your machine by running 'shutdown -h now', and then manually cutting power. A bit of a nuisance, but not the end of the world. b.
