well I have finally had a first stab at ACPI on the EPIA board. Based vaguely on the EPIA-M stuff ( some errors in that one I think) I have some problems to sort out, such as
irq 3: nobody cared (try booting with the "irqpoll" option) [<c0131f42>] __report_bad_irq+0x22/0x80 [<c013201d>] note_interrupt+0x5d/0xc0 [<c013195c>] __do_IRQ+0xdc/0x100 [<c01048ea>] do_IRQ+0x1a/0x30 [<c010322a>] common_interrupt+0x1a/0x20 [<c011acf1>] __do_softirq+0x31/0x90 [<c011ad76>] do_softirq+0x26/0x30 [<c011ae39>] irq_exit+0x39/0x40 [<c01048ef>] do_IRQ+0x1f/0x30 [<c010322a>] common_interrupt+0x1a/0x20 [<c0131bb9>] setup_irq+0xa9/0x130 [<c01dddb9>] acpi_irq+0x0/0x16 [<c01dddb9>] acpi_irq+0x0/0x16 [<c0131da4>] request_irq+0x74/0x90 [<c01dde25>] acpi_os_install_interrupt_handler+0x56/0x80 [<c01dddb9>] acpi_irq+0x0/0x16 [<c01dddb9>] acpi_irq+0x0/0x16 [<c01e2245>] acpi_ev_install_sci_handler+0x1a/0x1e [<c01e2208>] acpi_ev_sci_xrupt_handler+0x0/0x18 [<c01e1a45>] acpi_ev_install_xrupt_handlers+0x6/0x6b [<c01f2984>] acpi_enable_subsystem+0x53/0x55 [<c03b3443>] acpi_bus_init+0xc/0x89 [<c03b34fa>] acpi_init+0x3a/0x68 [<c03a679b>] do_initcalls+0x2b/0xb0 [<c01002c0>] init+0x0/0x150 [<c01002f2>] init+0x32/0x150 [<c0101375>] kernel_thread_helper+0x5/0x10
however my board did boot, although I didnt test it very much, but is does now actually switch off when I do a shutdown, which is progress.
