freebsd stable - Dec 2008 - 7.1-RC2 : ACPI warning and errors ACPI Error (psparse-0626)

Hello,

With 7.1-RC2 :

Dec 30 18:10:38 client1 kernel: FreeBSD 7.1-RC2 #0: Tue Dec 23 11:42:13 
UTC 2008
Dec 30 18:10:38 client1 kernel:

Stepping = 2

I have found following acpi warning and errors :

I don't see any direct wrong behaviour on the system.

Is anybody interested in more details ?

Best regards,
