Thanks for the report.  Can you send me the output of "lspci" and
your .config file?  I don't see any obvious problems with the drivers
I see mentioned in the boot log, but it would be easier if I knew
exactly which drivers to look at.

I'm confused.  I think the hang is related to IDE, but that
code all looks OK.  I expected to see a note about ACPI routing
the IDE interrupt, something like this:

> SIS5513: IDE controller at PCI slot 0000:00:02.5
  ACPI: PCI interrupt 0000:00:02.5[A] -> GSI XX (level, low) -> IRQ YY
> SIS5513: chipset revision 0

I don't see a path where the IDE device could be found without
that "ACPI: PCI interrupt ..." message being printed.

I also would have expected the hang to occur somewhere after the
"SIS5513: IDE controller at PCI slot 0000:00:02.5" message, but
apparently it happens *before* that.

Can you apply the following patch to 2.6.8-rc4-mm1 and collect all
the kernel output when booting with "pci=routeirq"?  It won't fix
the problem, but maybe it will give me some ideas.

It happens before the
  floppy0: no floppy controllers found
line.

Could there be a problem because the floppy driver doesn't find 
anything (there's currently no floppy drive in my computer)?

I tried disabling ACPI in my .config, and now 2.6.8-rc4-mm1 boots 
without requiring pci=routeirq...

Not only is your machine floppy drive-less, but the driver thinks you
don't even have a floppy *controller*, which I assume is separate
from the actual drive.

What mainboard do you have?  Does it boot without "pci=routeirq"
if you turn CONFIG_BLK_DEV_FD off?

The code in the floppy_init() -> user_reset_fdc() -> WAIT() ->
wait_til_done() -> reset_fdc() path looks pretty scary if there
really is no controller out there.  I'd feel much better if
we at least tried to use ACPI to figure out whether we have
a controller before we try to talk to it.

All that aside, I still don't see how the pci=routeirq change
would affect the floppy driver.  It does request_irq(6, ...),
and it is interesting that you have this:

    ACPI: PCI Interrupt Link [LNKD] enabled at IRQ 6
    ACPI: PCI interrupt 0000:00:04.0[A] -> GSI 6 (level, low) -> IRQ 6

which is for your NIC.  But the floppy controller isn't a PCI
device, so the LNKD enable shouldn't matter to it.

Let's see... you're using the PIC model.  Maybe the floppy driver
depends on the ACPI_IRQ_MODEL_PIC stuff in acpi_register_gsi()?
Can you post the contents of /proc/interrupts with the floppy
driver and "pci=routeirq"?  It seems weird to have the floppy
and the NIC share an IRQ, but it looks like that's what should
be happening.

Re: 2.6.8-rc4-mm1 doesn't boot

I've never understood this floppy IRQ6 business.
Apparently it requests IRQ6, but doesn't show up in /proc/interrupts

In any case, dropping a PCI interrupt on IRQ6 would surely break it
b/c that would set that IRQ6 to level trigger.

Before this change, did LNKD get set to something other than IRQ6?

I don't think so.  Adrian originally posted[1] a 2.6.8-rc3-mm1 boot log
(this was before the change):

	ACPI: PCI Interrupt Link [LNKD] (IRQs 3 4 5 *6 7 10 11 12 14 15)
	ACPI: PCI Interrupt Link [LNKD] enabled at IRQ 6
	ACPI: PCI interrupt 0000:00:04.0[A] -> GSI 6 (level, low) -> IRQ 6

Re: 2.6.8-rc4-mm1 doesn't boot

[Len Brown]

Does the system have any BIOS settings to enable/disable the floppy?
Is the floppy physically present on the system?

ACPI: PCI Interrupt Link [LNKD] (IRQs 3 4 5 *6 7 10 11 12 14 15)
        ACPI: PCI Interrupt Link [LNKD] enabled at IRQ 6

I assert it is a BIOS bug for the BIOS to set LNKD to
IRQ6 if there is a floppy present and enabled; but fair
game if there is no floppy.  Though perhaps floppy.c
doesn't understand that.

I have an ASRock K7S8X (it was the only Athlon board for under 30 Euro  
half a year ago...).

It boots without "pci=routeirq" only if I disable ACPI.

Yes, CONFIG_BLK_DEV_FD fixes the problem.

floppy_init() requests IRQ6, but then frees it before returning.  It
looks like the driver only holds onto it while the device is actually
open, which explains why it doesn't usually show up in /proc/interrupts.

Adrian has the floppies disabled in the BIOS, so maybe it's
legit to use IRQ6 for the NIC PCI interrupt.  But floppy.c
doesn't check for anything like that as far as I can see.

The fact that floppy.c seems to be able to poke the controller
and get an interrupt back (with "pci=routeirq") suggests to me
that the floppy controller responds even when disabled in the
BIOS, and that it actually expects IRQ6 to be level-triggered,
but the BIOS is leaving it configured as edge-triggered.

I suspect that the patch below will "fix" it.  I suppose we could
use a DMI-based quirk to poke this.  But it still feels like a
better solution would be to change floppy.c to:

	if (ACPI && (no floppy in ACPI namespace))
		return -ENODEV
	<poke around as we do today>

I expect that the the bug is that floppy.c, like other motherboard
devices, should take advantage of ACPI for device resource
enumeration.  This is one of the gaps I described at OLS,
and it is embodied in this bug report:
http://bugzilla.kernel.org/show_bug.cgi?id=2733

My expectation is that if the SETUP option is changed to
enable the floppy (the controller is probably burried inside
an LPC super-io or south bridge, even if there is no physical
drive in the box) Then we should see

ACPI: PCI Interrupt Link [LNKD] (IRQs 3 4 5 *6 7 10 11 12 14 15)
turn into

ACPI: PCI Interrupt Link [LNKD] (IRQs 3 4 5 6 7 10 *11 12 14 15)

with the * moving off of 6 (11 in this example) showing that
the BIOS selected a different active IRQ for this link.

Or even
ACPI: PCI Interrupt Link [LNKD] (IRQs 3 4 5 7 10 *11 12 14 15)

Where IRQ6 is not in the possible-list, which would prevent
Linux from setting the device to that IRQ even if we wanted to.
(and again, the '*' on some other IRQ, 11 in this example)

Adrian, if you enable your not-present floppy in the BIOS,
what does Linux do?

Adrian, can you try the following patch?  This is very sketchy start
at using ACPI to enumerate floppies.  This patch only checks for
a floppy controller (PNP0700) in the ACPI namespace.  If ACPI has
been disabled, or we actually find a controller, we probe blindly
for the floppy controller as we did in the past.  If ACPI is enabled
and we DON'T find a controller, we just exit with -ENODEV.

A more ambitious patch would actually look at the _CRS of the
controller and use the IRQ and DMA information from there instead
of the current hard-coded defaults.  But that's a lot more invasive
and likely to break things.  And since floppies are nearly extinct,
I'm not sure there's enough benefit to justify that.

This shows that we can make floppy probe fail,
but we also need to show that it can succeed.
If you enable the floppy in the BIOS does this
prink in bjorn's patch fire?:

+	printk("%s: found a controller at ACPI %s\n", DEVICE_NAME,
+               device->pnp.bus_id);
+       acpi_floppies_found++;

Also, it would be helpful to see the lines with LNKD
in the dmesg for floppy enabled and floppy disabled cases --
a 2.6.7 vintage kernel should work fine:

ACPI: PCI Interrupt Link [LNKD] (IRQs 3 4 5 *6 7 10 11 12 14 15)
        ACPI: PCI Interrupt Link [LNKD] enabled at IRQ 6

If you can also run acpidmp in both those scenarios
(any kernel version, ACPI enabled or disabled should do)
and send me the two output files, that would be great.

thanks,
-Len

ps. you can get acpidmp in /usr/sbin/ or from pmtools here

I've used 2.6.8.1, and in both cases I got the following (in the enabled 
case, no floppy was actually present):

ACPI: PCI Interrupt Link [LNKD] (IRQs 3 4 5 *6 7 10 11 12 14 15)
...
ACPI: PCI Interrupt Link [LNKD] enabled at IRQ 6
ACPI: PCI interrupt 0000:00:04.0[A] -> GSI 6 (level, low) -> IRQ 6

That's interesting, IRQ6 is being given to PCI, even when the floppy
controller is enabled.

you don't care about pmtest, just acpidmp.

cd acpidmp
make
