Hello,

I'm getting a lot of ACPI-errors afer my latest cvsup. I updated sources a
few hours ago, and the last time was the 23rd of April.

The error looks like this.

    ACPI-0293: *** Warning: Buffer created with zero length in AML
        -0166: *** Error: UtAllocate: Attempt to allocate zero bytes

The LAPv5 kernel is the same as GENERIC but with all SCSI and RAID stuff
taken out (except scbus and da which is still included).

Best regards,
Rasmus Skaarup
