Hi,

sending DMI info as suggested by dmesg output.

BTW does anyone have any idea about the parse errors?

thanks for the messages.
Please open a sighting here:
http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI

please attach the complete output from dmesg -s64000
and the output from acpidump.

Thanks for the acpidump (and bug report 9916)

I suspect that acpi_osi=Linux will work better than acpi_osi=!Linux on this box,
which is the case for the R61 and T61.  Perhaps you can verify that, say
by testing if sound and mute work in both cases?

It is hard to predict what acpi_osi=Linux will actuall do with this DSDT,
but it will have an effect on both the EC and SMM -- an effect
that appears to be intentional.

This is the most correct use of _OS and _OSI that I've seen --
as they set a different "interface" variable for each interface tested,
rather than trying to simply glean the latest Windows version known.

Indeed, the only thing I'd change is to move the test for "Microsoft Windows"
back with the !_OSI section with the test for NT.

Also, this may be the very first time I've seen a DSDT query for _OSI("FreeBSD").
Curiously, it sets \LNUX for it, just like for _OSI(Linux).  Which makes
me think that Lenovo is actualy booting something other than Windows
on this box -- b/c I've not seen that in any example BIOS...

thanks,
-Len
