I have no COM port on notebook (without port replicator which I do not have)
so COM is disabled in BIOS. No ttyS* is detected during boot (and no device
created) but I just noticed that serial modules are still loaded. Well, this
partially defeats the purpose of disabling COM port - the intention was to
free resources by *not* loading unneeded modules ...
This may have something to do with (ACPI) PnP which apparently believes COM is alive.
Notebook is Toshiba Portege 4000.

Can you cat /sys/firmware/acpi/DSDT and use iasl to decode it?
it seems that your BIOS has problem about com setup.

Nice... What's this then?

0x3f8-0x3ff is COM1 and a 16550A is the most common invocation of the
vernerable serial port. I haven't seen a real 8250 in ages. the 16550
is an 8250 with larger FIFO's and better rates.
Now, it's on IRQ5 instead of IRQ4 but that's all allocatable on PCI.
Unless I'm missing something, it looks like you've got a COM port and it
looks like it's active.
Might be related to an IR port?

This doesn't mean that a port (ie connector) is present. My notebook
also has the electronics without the physical connector.

DSDT attached.
To illustrate the problem. Here is what I get booting exactly the same kernel
with the only difference that COM is enabled in BIOS:
[ 147.721790] Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing enabled
[ 147.722658] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[ 147.813557] 00:09: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
When COM is disabled I get
[ 235.865683] Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing enabled
[ 236.221995] serial 00:09: activated
No ttyS0 - and it is correct.
I'd expect that either serial driver should not be loaded at all in this case.

Probably a BIOS bug. It still lists the port in PnP data even though the
hardware is disabled, so the kernel still tries to load the serial
driver for it, which finds there's no port there.

Here is what we get from _STA:
[ 1689.988245] HID=PNP0501 flags=0d
If I read specs correctly, if bit 1 is cleared it means, device is not able
to access its hardware resources, so it makes no sense to even try to
load driver for it.
And of course it makes PnP output completely bogus:
00:09 PNP0501 16550A-compatible serial port
state = active
allocated resources:
io 0x3f8-0x3ff
irq 5
So two questions:
1. why device got enabled when ACPI explicitly stated it cannot be?
2. can we get information about _STA result in user space so we do not try
to autoload driver for device that can't work?

0xd means present, disabled. A disabled PNP device can be enabled, ACPI
doesn't say it can't be. When the driver is loaded, it will enabled the
device. If BIOS wants to disable the device, it should make the device
non-present.
