Hi,
Just for larks, I decided to iasl -d my SSDT, and found the following
horridness:

To make it compile nicely, I looked at the DSDT and fixed up the
external method calls (Much of the typing in the External definitions
was wrong), checked the number of arguments, and noted the missing
parenthesis around the arguments which should have been passed to these
calls. (Possibly a decompile bug due to the erronous External()
definitions?)

Does this fix seem reasonable to anyone.. how can I override the SSDT in
linux (I've got the DSDT over-ridden, no problem).
Clearly to verify this properly, I need to post the DSDT and SSDT in
their entirety, please let me know if I should post them to this list,
or privately email me and I'll send them.
Are these problems "real", or are they simply the symptom of decompiling
the SSDT in the absence of context from the DSDT?
Regards
Peter Clifton
