In reply to both Don and Martin.
I had completely expurgitated the 2.6.8 from my system,
but I downloaded it again, reinstalled it, rebooted in recovery mode,
and saved the /proc/config.gz,
then confirmed that it does indeed halt everything with shutdown -h.
The ACPI options are set as follows:
# ACPI (Advanced Configuration and Power Interface) Support
# CONFIG_ACPI_SLEEP is not set
# CONFIG_ACPI_DEBUG is not set
# CONFIG_SERIAL_8250_ACPI is not set
The CONFIG_ACPI_SLEEP option is irrelevent, as we are not
trying to send the system to sleep.
ACPI is a standard. The kernel isn't supposed to vary from board to
board. If the hardware doesnt poweroff when its told to, then its the
fault of the hardware. It's up to the manufacturer
to program their bios so their board shuts down properly.
Perhaps we should try to find a tyan s2875 that actually works
properly with multiple versions of linux. If there are none,
then we know its the fault of the board design.
