Correction to my previous comment regarding: "file /DSDT.aml not found". Don't know what I was thinking when I wrote that! This is normal. It simply means you haven't provided a custom DSDT ie. you are using DSDT in BIOS. However, having said that, the error message you report does result from a poorly constructed DSDT in BIOS. Again, this is not uncommon. All other previous comments still stand.
