>Description:
# dmesg | grep acpiwmibus
acpiwmibus at acpiwmi0 not configured

Oh? Let's fix that.

# egrep acpiwmibus /usr/src/sys/arch/amd64/conf/GIFT
acpiwmibus*     at acpiwmi?             # ACPI WMI Bus support
wmidell*        at acpiwmibus?          # Dell WMI mappings
wmieeepc*       at acpiwmibus?          # Asus Eee PC WMI mappings
wmihp*          at acpiwmibus?          # HP WMI mappings
wmimsi*         at acpiwmibus?          # MSI WMI mappings

Uncommented the first line there.

# ./build.sh -O /usr/obj -T /usr/tools kernel=GIFT
[...]
===> Build directory:     /usr/obj/sys/arch/amd64/compile/GIFT
(cd /usr/obj/sys/arch/amd64/compile/GIFT && rm -f a.out [Ee]rrs mklog core *.core .gdbinit || true)
/usr/src/sys/arch/amd64/conf/GIFT:297: acpiwmibus*: unknown device `acpiwmibus'
*** Stop.

ERROR: nbconfig failed for GIFT
*** BUILD ABORTED ***

>How-To-Repeat:
	I don't really understand this. How is acpiwmibus detected unconfigurated at
boot time, but cannot be added in the kernel config file? Moreover, why doesn't
build.sh complain if the initial acpiwmibus line is commented while its child
lines are left uncommented?

 Where did you get that from?

 I only see this in GENERIC:

 acpiwmi*        at acpi?                # ACPI WMI Mapper
 wmidell*        at acpiwmibus?          # Dell WMI mappings

 I assume that the manpage is either out of date or the default kernel
 configs are wrong. This looks like config(9) magic.

 What happens if you add
  acpiwmi* at acpi?
 and remove the
  acpiwmibus* at acpiwmi?
 line?

 That's the current setup. NetBSD 6.0_RC1 dmesg in PR/46919. You can see the
 behaviour there.

State-Changed-When: Thu, 01 Nov 2012 07:30:55 +0000
State-Changed-Why:
The line "acpiwmibus at acpiwmi0 not configured" means that a WMI device was
located but no child devices were found for it. There is no bug here.

 Which brings us now to the manpage of acpiwmi(4) which suggest that
 the kernel config needs an addtional line: acpiwmibus* at acpiwmi?

the doc bug was fixed back when this was initially closed; that just wasn't
relayed into gnats.
