What is weird is:
1
[ 3.970863] ACPI: SCI (IRQ9) allocation failed
[ 3.970906] ACPI Exception: AE_NOT_ACQUIRED, Unable to install System
Control Interrupt handler (20110413/evevent-119)
[ 3.970911] ACPI: Unable to start the ACPI Interpreter
IRQ9.. It looks like it really wants to use 9 instead of 20.
Looking at the code it does:
144 status =
145 acpi_os_install_interrupt_handler((u32)
acpi_gbl_FADT.sci_interrupt,
146 acpi_ev_sci_xrupt_handler,
147 acpi_gbl_gpe_xrupt_list_head);
So it uses the acpi_glb_FADT.sci_interrupt. I think the best path
is to stick a bunch of printks in drivers/acpi/osl.c in
acpi_os_install_interrupt_handler
and see what gsi, acpi_gbl_FADT.sci_interrupt, and what 'irq' end up being.

Ok, let me look at them in some more details.
