System: NetBSD kaeru 2.0F NetBSD 2.0F (build.kaeru) #1372: Thu Jun 3 20:35:27 JST 2004 takashi@kaeru:/home/takashi/work/kernel/build.kaeru i386
Architecture: i386
Machine: i386
>Description:
	acpi power down fails on VA Linux 1222.
	VA Linux 1222 seems to be an OEM version of NEC Express 5800/120Ra-1.
	(i'm not sure about the NEC model name.)

	Linux 2.4.24 (acpica 20031002) has the problem.
	Linux 2.4.18 (acpica 20011018) works fine.

	if needed, i can provide dmesg, fadt, etc.
>How-To-Repeat:
	try poweroff(8) on the machine.
>Fix:
	the following is a workaround.
	- enable acpi unconditionally as old versions of acpica.
	  (the machine seems to have ACPI_BITREG_SCI_ENABLE set on boot.)
	- keep acpi enable on shutdown as linux.
	  (the machine won't power down after AcpiDisable.)
