It's a netmos 9835 serial card with 2 ports. PCI, there is no PCIe in
the machine as far as I can see.
Can they
tell what IRQ the device is reportedly using in Windows and if it
matches what Linux reports?
I can ask them. 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.
Well, you can see if Windows shows IRQ 10 or 11 for that device..
