Sorry, I am a newbie at this.

I did this: cp /proc/acpi/dsdt .; iasl -d dsdt

This yields a file called dsdt.dsl, which does not contain any string
like _CST or P_BLK. What am I doing wrong here?

Attached is the file in question.

Try #2 with gzipped output to keep the size down. Sorry for the inconvenience.
