When was your first > encountered of this hang? By the time you get to the ACPI powerdown being called, all services will have stopped anyway. If you want to turn off acpi, use acpi=off at the kernel command line. Other things to try (from Documentation/kernel-parameters.txt): acpi= [HW,ACPI] Advanced Configuration and Power Interface Format: { force | off | ht | strict } force -- enable ACPI if default was off off -- disable ACPI if default was on noirq -- do not use ACPI for IRQ routing ht -- run only enough ACPI to enable Hyper Threading strict -- Be less tolerant of platforms that are not strictly ACPI specification compliant. See also Documentation/pm.txt, pci=noacpi Hope this helps, James. -- E-mail address: james | +--------------Information------------------+ @westexe.demon.co.uk | | Killed user #23.
