Nate,

Please send a listing of the _BST errors that appear on the IBM machines
and the related DSDT.  This issue isn't really an ACPI 2.0 issue, it
extends back to ACPI 1.0.  I'd like to solve this once and for all if
possible.

Bob




This patch reverts part of 0619 to fix _BST errors on IBM thinkpads (and
others.  It appears many ASL versions do not implement the alluded to
2.0C copy semantics.

My acpidump output is here:
   http://www.root.org/~nate/acpi/ibm-acpidump.asl.gz

You can easily see the problem since method _BST returns the value of
a call to _GBST.  Here is a link to my original message with dmesg output:
   http://home.jp.freebsd.org/cgi-bin/showmail/acpi-jp/2408

BTW, I am close to isolating a panic caused by resource lists (in this
case _CRS) overflowing the allocated buffer.
