This patch should fix multiple user-visible problems with the ACPI IRQ
routing after S3 resume:
"irq x: nobody cared"
"my interrupts are gone"
It probably applies to multiple bugzilla entries and mailing list posts.
Tested on my machine, which is experiencing similar problems. Seems to
work - although I get some non-fatal "nobody cared" messages that might
be caused by the i8042 driver.
Comments?
Stefan, can you test this?

I was under the (apparently false) impression that devices would
call eg. pci_enable_device() upon .resume, which would bubble down
to pcibios_enable_irq()/acpi_pci_irq_enable() which would handle this.
But not all do this this, and
for those that do, the link->irq.setonboot test in
acpi_pci_link_allocate would prevent the hardware from being
reprogrammed anyway -- so I guess I hadn't thought this path through.
And so I think we do need this patch for chipsets that clear
the IRQ routers upon suspend. Indeed, it is likely that
we'd have this problem in S4 in addition to S3, yes?

This declaration isn't necessary b/c the definition (below)
is above where the function is first used, yes?

I think that before this change, irq.setonboot was a NOP
and a candidate for being deleted. However, it does seem
to have a use here, where we want to re-program only those
links that were programmed. ("setonboot" would probably
be better called "initialized" or "programmed").
Since irq.active is set for all links from probe time
whether or not we program them, it isn't sufficient,
as we've found from experience that it is a bad idea
to program links that are not explicitly requested
by actual devices -- so I agree we need setonboot here.

I think that testing acpi_noirq is sufficient here.

Sorry for the very late reply.
I tested with 2.6.8.1(I think your patch it included there) with strange
results.
*It works fine if I unload ipw2100 before suspend and load it later
*In single user mode with ipw2100 loaded while S3, IRQ 11 is disabled on
resume, IRQ is not disabled
*When the system is fully booted up, everything seems to work fine.
I'll test a little bit more and report the results.
Cheers,
Stefan

I can't find anything named "ipw2100" in my kernel source tree...

Huh? IRQ(what) is not disabled?
Please attach dmesg.
> *When the system is fully booted up, everything seems to work fine.
What do you mean by this? If you suspend when more drivers are loaded,
things work fine, but don't work when less drivers are loaded?

The driver for the Intel wlan card. See ipw2100.sf.net

Ooops, I forgot the number.
IRQ 10 is not disabled any more. I verified that it works fine.

Yes, I meant this. But it looks like another once-and-never-again success. I
recompiled my kernel and now the ipw2100 resume also fails when all drivers
are loaded.
Is it possible that the IRQ routing is restored too late? ipw2100 reports a
lot of unhandled irqs.
A dmesg is attached.

Stefan -
Can you please attach 'cat /proc/interrupts' from a system that has all
possible drivers for your hardware loaded. From before suspend.
Also - did suspend/resume for the ipw2100 ever work under any kernel
version?
Thanks.
Nathan

Yes, it works with acpi=noirq at least up to 2.6.7(not tested with later
versions, but I'm sure it does)
It works with 2.6.8-rc2 and 2.6.8-rc4 and 2.6.8.1 with acpi IRQs and a
modified dsdt which forces LNKE to IRQ 10. I attached a dmesg output of a
successful resume.
Cheers,
Stefan
