Solution to "No pointer back to NS node in buffer"

[Eugene Grosbein]

Hi!

Famous ACPI warning "No pointer back to NS node in buffer"
and some other ACPI exceptions were resolved for my 7.2-STABLE system
by upgrading acpica from stock version 20070320 to 20090521.

I took http://people.freebsd.org/~jkim/acpica-import-20090521.diff.gz
and corrected it for today's RELENG_7. It is available here:

ftp://www.kuzbass.ru/pub/freebsd/acpica-import-20090521-7.diff.bz2

It "works for me".
