> ACPI: setting ELCR to 0200 (from 0440)
Both the working 2.6.23 and the failing 2.6.24 are setting IRQ9
to level triggered.
When you boot 2.6.24 with acpi_sci=edge, it is likely that
you are disabling all ACPI interrupts (except the first one).
On a working system, you should be able to kill acpid
(simply to disable the action on the interrupt)
and press the power or lid buttons and see /proc/interrupts increment.
I expect with acpi_sci=edge, "grep acpi /proc/interrupts" will stay at 1.
If you boot 2.6.24 with CONFIG_ACPI_SBS=n, does "grep acpi /proc/interrupts"
still show the acpi interrupt increasing at a high rate?
Please boot the latest 2.6.25,
# cd /sys/firmware/acpi/interrupts
# grep . *
# grep acpi /proc/interrupts
and paste the output here
