           Summary: halt and poweroff do not shut the system down
           Product: ACPI
           Version: 2.5
     KernelVersion: 2.6.22.1-rt9
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Power-Off
        AssignedTo: acpi_power-off at kernel-bugs.osdl.org
        ReportedBy: linux.kernel at free.fr


I'm using a PREEMPT_RT kernel.
http://rt.wiki.kernel.org/index.php/Main_Page

When I run 'halt' (from sysvinit-2.86) the kernel prints:

Halting.
Shutdown: hdc
ACPI: PCI interrupt for device 0000:01:05.0 disabled
ACPI: PCI interrupt for device 0000:01:04.0 disabled
ACPI: PCI interrupt for device 0000:01:03.0 disabled
ACPI: PCI interrupt for device 0000:01:02.0 disabled
Power down.
acpi_power_off called

But the system does not shut down. (The fans keep spinning, the LEDs keep
shining, the LCD keeps displaying.) Basically, the motherboard is still
providing power to every component, as if the power supply had refused to stop.

Same behavior when I run 'poweroff' instead of 'halt'.
