           Summary: Rocky III+ RK886EX hangs on initrd loading
           Product: ACPI

     KernelVersion: 2.6.20.1, 2.6.22.1
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1

Most recent kernel where this bug did not occur: ?
Distribution: Debian
Hardware Environment:
Software Environment: PXE-booted kernel, with some custom initrd

--- Problem Description:

Kernel boots, but hangs with a blank screen shortly after "checking if image is
initramfs" (some messages scroll by), unless "acpi=off" or "acpi=ht" is given.
"acpi=force", "acpi=strict", "pci=conf1", "acpi=noirq", "pci=noacpi", 
"noapic hda=noprobe hdc=noprobe" don't help.

The initrd doesn't clear the screen; maybe it's some kind of powersaving that
kicks in and kills the machine.
No NumLock, no SysReq.

--- Steps to reproduce: Booting the kernel.
