When booting the machine you see this ACPI error message in syslog:
<4>ACPI Error (dsfield-0139): [CAPD] Namespace lookup failure, AE_ALREADY_EXISTS
<4>ACPI Error (psparse-0530): Method parse/execution failed [\_SB_.PCI0._OSC]
(Node 8800bef02fd0), AE_ALREADY_EXISTS
<4>ACPI: Marking method _OSC as Serialized because of AE_ALREADY_EXISTS error
The reason is the same (name) CreateDWordField (CAPD) is tried to be
created several times. While there is no negative side effect known yet,
this should be addressed as it could have sever side effects.
Scott: I try to figure out the correct ACPI code that should be added to
the BIOS, could you add someone from HP who can take care of and look at
this then, please.

Hi Bob, can you help finding the correct ASL code to suggest to HP,
please.
The problem is (with all occurrences of the multiple times created CAPD):
...
While (Local0)
{
CreateDWordField (CAPB, Local1, CAPD)
...
And (CAPD, 0x09, CAPD)
...
Store (Zero, CAPD)
...
If (And (CAPD, 0x08))
...
}
...
I wonder how this should be converted into correct ASL code. There is AFAIK no
way of undeclaring the CAPD object. It might work with using Index (CAPB,
Local1) where CAPD is currently used. The offset should still be the same, not
sure whether:
Store(Zero, CAPD)
and
Store(Zero, Index(CAPB, Local1)
would be the same or whether in the first case a whole DWord is zeroed.
But there might be a more elegant way of solving this.

A good way to create dynamic objects it to put them in a subroutine. I would
add a new method that is called from within the loop. The code below should
suffice.
However, I find this statement odd:
Store (One, Local1)
This means that the input buffer is (DWORD) accessed at offsets 1, 5, 9, 13,
etc., instead of what I would expect: 0, 4, 8, 12, etc. It probably should be a
store of Zero to Local1.
