It's a netmos 9835 serial card with 2 ports.

What I know is that with acpi=noirq (or with the quirk) the IRQ number is 10, with acpi without the quirk, it's 11: PCI: setting IRQ 2 as level-triggered serial 0000:00:09.0: found PCI INT A -> IRQ 2 0000:00:09.0: ttyS4 at I/O 0x1898 (irq = 10) is a 16550A 0000:00:09.0: ttyS5 at I/O 0x1890 (irq = 10) is a 16550A ACPI: PCI Interrupt Link [LNKB] enabled at IRQ 11 PCI: setting IRQ 11 as level-triggered serial 0000:00:09.0: PCI INT A -> Link[LNKB] -> GSI 11 (level, low) -> IRQ 11 0000:00:09.0: ttyS4 at I/O 0x1898 (irq = 11) is a 16550A 0000:00:09.0: ttyS5 at I/O 0x1890 (irq = 11) is a 16550A I still no point in comparing this to Windows' setup. We can't find out whether it is quirked or better (without some bug) handled there. regards, -- js suse labs -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
