Can you isolate this regression to a specific release?  There have been
several changes to arch/i386/kernel/irq.c since 2.6.0-test7.  Also, it
would be interesting to know if it also happens with CONFIG_SMP=n (but
with the IOAPIC still enabled)  Plus, a sanity check of the rate of
interrutps reported by /proc/interrupts might yield a clue.

thanks,

ps.
You can avoid the symptom by booting with "noirqdebug" or having the
interrupt handling always return IRQ_HANDLED.  But then we'd lose the
means to find out why the driver is receiving interrupts for which it
can find no cause.

Thanks for the response, Len.  If I can identify which kernel triggered
the problem I'll let you know.  It will be tricky, since it takes a day
or more to appear.

For the record, I've figured out why no one ever submitted the driver:
I somehow didn't notice the binary-only module in the middle of the
rest of the code.  The main interrupt handler is in there.  The driver
wrapper returns IRQ_NONE if some blob of code in there decides the card
didn't generate an interrupt, so it could be anything.  I see that
there's now a reverse-engineered ALSA driver for this card so I'm going
to see if that works first.

I still haven't figured out which kernel first introduced the problem,
but it's still present, at 2.6.5.  I didn't see it while I was running
2.6.3-rc3, for some reason.

Now I'm using the ALSA au8830 driver.  There was no output from the
driver before the nobody-cared message, so it was caused by one of
these (sound/pci/au88x0/au88x0_core.c):

        //check if the interrupt is ours.
        if (!(hwread(vortex->mmio, VORTEX_STAT) & 0x1))
                return IRQ_NONE;

        // This is the Interrrupt Enable flag we set before (consistency check).
        if (!(hwread(vortex->mmio, VORTEX_CTRL) & CTRL_IRQ_ENABLE))
                return IRQ_NONE;


About a minute after this happened, USB did the same thing:
Apr  6 12:21:40 nevyn kernel: irq 11: nobody cared!
Apr  6 12:21:40 nevyn kernel: Call Trace:

Apr  6 12:21:40 nevyn kernel: Disabling IRQ #11

That's the UHCI driver.  The code in question is presumably:
        status = inw(io_addr + USBSTS);
        if (!(status & ~USBSTS_HCH))    /* shared interrupt, not mine */
                return IRQ_NONE;
        outw(status, io_addr + USBSTS);         /* Clear it */

I'm assuming that it is not the fault of either of these drivers, since
both of those are quite straightforward; they appear to be actually
being triggered when nothing is going on.

There was a set of APIC errors an hour before, but they're probably
unrelated:
Apr  6 11:31:31 nevyn kernel: APIC error on CPU1: 00(08)
Apr  6 11:31:31 nevyn kernel: APIC error on CPU0: 00(02)
Other than that, no interesting information in the logs.

The rate of interrupts looks sane.  I'll try to check it the next time
this happens but I didn't see anything strange.

Afraid that's not enough info for anyone to help :(  I'll try a couple
of things...

It's this one.  If I wait until it locks up - it did at exactly 600,001
interrupts, interesting... then reload the module with this:
        //check if the interrupt is ours.
        if (!(hwread(vortex->mmio, VORTEX_STAT) & 0x1))
{
		printk ("vortex: Interrupt not ours\n");
                return IRQ_NONE;
}

I get _exactly_ 100,000 copies of that printout, and then the interrupt
is disabled with a 'nobody cares' response.  The first time, all
100,000 were on CPU0; the second time, 2 were on CPU0 and the other
99,998 on CPU1.

So it looks as if something gets wedged, and then the interrupt fires
continuously for no reason.

I'm *completely* stabbing in the dark, but ISTR lots of problems with
Vortices (?), even on Windows, were caused by the card not being on the
bus master PCI slot (which is typically the first one on most
motherboards.) Possibly the IRQ assignment depends on the location of the
card?

Actually I am using my Vortex2 in a non-mastering PCI slot right now so
maybe that's not the problem. But I'm using the snd-au8830 driver and it
seems to work just fine in 2.6.5-mm1.

I'm most likely completely wrong, so feel free to correct me.

If IRQ initialization is done incorrectly, it is possible
For a driver to request_irq(X), while the hardware is actually
on IRQ Y.

Then when that device becomes active, it would kill the other
devices on Y because its handler is looking for interrupts on X.

If this happens with acpi enabled, but doesn't happen with acpi=off
or pci=noacpi, then we need to compare the /proc/interrupts between
the working and failintg configs to see if the IRQs have moved around
when perhaps they should not have.  Dmesg from the ACPI case would
also be needed.

I believe this is due to transient hardware errors on your MB.
Though not fatal, it isn't a good indicator.

Thanks for your continued help... this gave me some extremely
interesting data.  Here's some data from /proc/interrupts on
2.6.0-test9, which was quite stable for me:
 19:          0          0   IO-APIC-level  au88xx
 21:         52          0   IO-APIC-level  uhci_hcd, uhci_hcd

2.6.5 with ACPI:
 11:     300000          0   IO-APIC-level  uhci_hcd, uhci_hcd
 19:     299999          1   IO-APIC-level  au8830

2.6.5 with pci=noacpi:
  5:         54          1   IO-APIC-level  uhci_hcd, uhci_hcd, au8830

I haven't run that third setup for a lot of time yet, so I don't know
for sure that it's stable.  Sound seems much more crackly than it was
with ACPI enabled, but that could be any problem with the vortex2
driver - or it could be missing interrupts.

Here's one interesting bit that only appears in dmesg with ACPI
enabled, and only in 2.6.5:

PCI: Via IRQ fixup for 0000:00:07.2, from 5 to 11
PCI: Via IRQ fixup for 0000:00:07.3, from 5 to 11

That's the two UHCI devices.  So they get quirked off to a different
IRQ, and au88x0 somehow ends up routed to yet a third IRQ, but from the
symptoms I am guessing that the USB and au8830 are actually connected
to the same pin.  That would explain both of them getting interrupts
with no obvious source, even though they do each get their own
interrupts also.

The quirk isn't new; it's from 2002.  So presumably ACPI is now putting
them somewhere different than it used to.  Here's a some bits of the dmesg:

2.6.0-test9

I've attached the dmesgs and /proc/interrupts.



In the interest of full disclosure, this motherboard came with a bad
_PRT.  There are a four entries in the APIC-mode _PRT which look like:
            Package(0x4) {
                0x0007ffff,
                0x0,
                0x0,
                \_SB_.PCI0.LNKA,
            },

With that, ACPI complains and/or can't boot (don't remember exactly). 
So I've fudged them to:
            Package(0x4) {
                0x0007ffff,
                0x0,
                \_SB_.PCI0.LNKA,
                0x0,
            },

I made this change some months before the 2.6.0-test9 kernel which
worked OK.

Re: 2.6.2-rc3: irq#19 - nobody cared - with an au88xx

[Daniel Jacobowitz]

[Jeff, I'm sending this to you because your name is above the Via PCI
quirks.  It's in a followup comment, though, so there's probably
someone else I should be talking to about the original quirks - I just
haven't worked out who yet.]

I'm trying to track down an interrupt routing problem on my Via-chipset
motherboard (it's an Abit VP6).  The symptoms are that the USB and
audio drivers eat each other; it appears that they are on the same
IRQ line, even though /proc/interrupts says:
 11:     300000          0   IO-APIC-level  uhci_hcd, uhci_hcd
 19:     299999          1   IO-APIC-level  au8830

So eventually one of them gets wedged on, and the other panics because
it can't identify the incoming interrupts.

At boot I see this, from drivers/pci/quirks.c:

PCI: Via IRQ fixup for 0000:00:07.2, from 5 to 11
PCI: Via IRQ fixup for 0000:00:07.3, from 5 to 11

Is it possible that the same problem, i.e. writes to the INTERRUPT_LINE
register causing connection to the PIC, could apply to devices in the PCI
slots?  The register still shows 5 for the au8830, which is the IRQ it
gets assigned to if I boot without ACPI.

I know this hypothesis sounds a little weak.  I'm running out of ideas
:)

I've worked out the part of the problem involving that quirk.  There's
an entry in quirks.c which reads:

/*
 *      VIA northbridges care about PCI_INTERRUPT_LINE
 */

int interrupt_line_quirk;

static void __devinit quirk_via_bridge(struct pci_dev *pdev)
{
        if(pdev->devfn == 0)
                interrupt_line_quirk = 1;
}

The i386 pirq_enable_irq honors this:
        /* VIA bridges use interrupt line for apic/pci steering across
           the V-Link */
        else if (interrupt_line_quirk)
                pci_write_config_byte(dev, PCI_INTERRUPT_LINE, dev->irq);

The matching function in ACPI does not honor this quirk, so we probably
have routing troubles on a lot of affected VIA northbridges.  There's
at least one thing which looks like an example of this in Bugzilla
(which was "fixed" by twiddling the IRQ balancing code).  With this
patch I get a little better (more predictable, at least) behavior.

On the down side, this doesn't fix everything.  I can observe that with
XMMS paused and my USB trackball untouched, I get no interrupts to
either the au88xx's IRQ or the UHCI's IRQ.  But with the sound playing,
I get about 1.8 times as many IRQs reported to the USB controller as I
do to the sound card!  I assume vice versa is true also, though I can't
check right now (both are wedged again).

Something else is still cross-connecting the USB IRQ (11) and the
au88xx IRQ (19).  I had hoped it was the above problem, but it appears
not.  I hand-verified that PCI_INTERRUPT_LINE now agrees with
/proc/interrupts for everything - except for the bridge itself; Jeff
Garzik's comment in quirks.c suggests that this is expected.

Any ideas on what could cause this are much appreciated.  Should I use
bugzilla to track this problem?

You're certainly on the right track.  Len and I have discussed how to 
best handle this in ACPI, I'll let him comment further...

2.6.2-rc3: irq#19 - nobody cared - with an au88xx

[Daniel Jacobowitz]

I've started getting this, every 24 hours or so:

irq 19: nobody cared!
Call Trace:
 [<c010d38a>] __report_bad_irq+0x2a/0x90
 [<c010d480>] note_interrupt+0x70/0xb0

handlers:
[<f886b290>] (au_isr+0x0/0xb0 [au8830])
Disabling IRQ #19

and then sound doesn't work for a while.

There's a good chance this is my fault.  IRQ 19 is:

 19:   18500001          0   IO-APIC-level  au88xx

and the au88xx driver is an out-of-tree driver that was developed on
2.4/early-2.5, and I ported it to 2.6 myself.  It worked flawlessly on
2.6.0-test7; has something changed in how interrupt handlers are required to
behave?

[Just ask if you actually want the source to this driver... I don't know
enough about the card to actually submit it to Linus's tree and the driver's
original authors aparently didn't care to.]
