Good point you raised here tsanghan , however there's one thing I did not understand well, does it mean your motherboard is older than the year 2000 ? If not it just shows that there is something really wrong with the ACPI section in the actual kernels.
For my system, the Tyan Tiger K8W, it is at most older than september 2003, I bought mine last year and I did the Bios upgrades. -- System does not power off on shutdown https://launchpad.net/bugs/36158 _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
