Have the same problem here.
2.6.24 works, 2.6.28 doesn't (tried 2.6.8-ARCH and 2.6.28.7-1-ARCH).
I reported the problem to alsa-devel list, but they said I have hw
problems (I think I do not).

The latest arch kernel gives oops, if the card is inserted before booting.
It crashes during udev event processing (i.e. something from userspace
triggers the problem)
If anybody is really interested, I can try to provide kernel backtrace
(either type it in, or try to use serial console).

Could you check the latest sound git tree to be sure?

   git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git

Also the problem might be rather the cardbus side...

Oops is bad, and yes, it'd be helpful if you can show the backtrace.

Does not oops.
But the card does not work either.

> Also the problem might be rather the cardbus side...
I suspect, too.
Because it works in my laptop. But fails on a desktop with pci-cardbus adapter.

No serial console :( My new M/B have only pin header and no rs232
jack. Need to find/build an adapter.
So. what I see (without stack addresses and some offsets):

That explains.  A PCI-board is often problematic...

Looks like an accessing to the uninitialized device.
Does the patch below fix?

We should initialize spinlock & co at the very beginning, though...

Yes.
2.6.28-ARCH + your patch fixes oops.
Cards still does not work though.

If I additionally apply Tim's patch, I get (coldplugged)
NULL pointer dereference at 0000000000000140

IP: snd_hdsp_interrupt + 0x9c/0x220

Trace:

handle_IRQ_event
handle_fasteoi_irq
do_IRQ
ret_from_intr
flat_send_IPI_mask
mwait_idle
cpu_idle


Hotplugging just disables the card (as "usual").

Of course, it's totally irrelevant :)

What is Tim's patch?  Could you attach or give the commit id if it's
already in the git tree?

takashi applied it to the sound-2.6 git repository:

Weird.  It's just adds more check in snd_hdsp_load_firmware_from_cache(),
but has nothing to do with the interrupt handling.

I checked kernel with your patch only, and with Tim's patch added.
I did it twice, every time building from scratch.

Btw, with 2.6.24 the card does not work also, it's can't load firmware.
This all started after upgrade. I now have Asus P5Q board (Intel P45 chipset).
I think I should test the card in another 2 PCI slots.

That patch just deals with the problems introduced with the new power
managment in 2.6.28 - the cardbus slot seems to be powered up later so
the card isn't initialized yet when the driver is loaded.

Hmm, but how the bug comes up in the interrupt context after patching?

Sorry, getlemen
my bad.

I'd better checked sources twice.
I took  -F option of patch not as serious, as it deserves, and it
messed interrupt handler.
After manual patching, everything looks nice and does not oops anymore.
