RE: one more ACPI Error (utglobal-0125): Unknown exception code: 0xFFFFFFEA [Re: 2.6.18-rc4-mm3]

As far as the unknown exception,

>[ 9.392729] [<c0246fb6>] acpi_ut_status_exit+0x31/0x5e
>[ 9.393453] [<c0243352>] acpi_walk_resources+0x10e/0x11b
>[ 9.394174] [<c025697e>] acpi_motherboard_add+0x22/0x31

I would guess that the callback routine for walk_resources is returning
a non-zero status value which is causing an immediate abort of the walk
with that value -- and the value is bogus.
