any update on the pcmcia bug blocking Audigy2 notebook sound card driver development

any update on the pcmcia bug blocking Audigy2 notebook sound card driver development

[Raymond Lai]

Hi all,

I remember there's a kernel pcmcia bug preventing the development for 
the Audigy2 pcmcia notebook sound card driver. 

See http://www.alsa-project.org/alsa-doc/index.php?vendor=vendor-Creative_Labs#matrix

Is there any new updates on the situation? Has the bug been fixed? or
anyone working on it?

Thanks,
Raymond

Is it related to http://bugzilla.kernel.org/show_bug.cgi?id=4788 ?

No, that was a known issue that is resolved in 2.6.13-rc*.  This is the
bug he's referring to:

http://lkml.org/lkml/2005/7/11/265

Looks like James never followed up, probably due to OLS.

Thanks, Lee. That's the bug I'm referring to.

It would be great if laptop users can enjoy the higher sound quality
the Audigy2 pcmcia sound card offers, which is way better than the
builtin onboard sound.

I think not, the card in question is the Creative Audigy 2 ZS PCMCIA
card. I have one I can't use yet :-( The kernel locks hard when ALSA
tries to load the driver. 

This is the last I heard about this issue:

Maybe we should have the emu10k1 driver not claim the device until this
is fixed.  It's better than locking the machine (this behavior has been
confirmed by several other users).

It seems to have the same PCI ID.  If the probing phase already
triggers the hang up, we can't stop it.

The PCI ID is the same, but the subsystem ID is different. All PCI 
probing works ok, so we can detect it and disable the driver for now.
The hang happens on the first inb/w/d(.) function call. outb/w/d() 
commands do not hang the system.
I don't really see the point of changing anything. The system might 
hang, but just removing the PCMCIA card gets everything going again.
It is still a PCMCIA cardbus bug in the kernel that is the real cause. I 
have had very little time recently to look at it. It is extremely 
difficult to track down the reason for this bug, so I think that fixing 
this is a long way away at present.

Well the LKML thread ended (before OLS) with the kernel developers
asking you for /proc/ioports and other info and I never saw it.  Maybe
we will get lucky and they'll be able to fix it quickly.
