Oops with snd-ymfpci and ALSA 0.9.3a

Oops with snd-ymfpci and ALSA 0.9.3a

[Josh Green]

[-- Attachment #1: Type: text/plain, Size: 320 bytes --]

I upgraded to ALSA 0.9.3a from 0.9.2 and am getting a kernel oops upon
insertion of the snd-ymfpci module. I've attached the output from
ksymoops. This is with stock kernel 2.4.20 on a Panasonic laptop and
Mandrake 9.1. I downgraded back to 0.9.2 which works fine. I can provide
more info if needed, cheers.

ksymoops 2.4.8 on i686 2.4.20.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.20/ (default)
     -m /boot/System.map-2.4.20 (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

This is a bug in 0.9.3, it has been fixed on CVS.

My Toshiba Tecra (uses YMF-744B) still does not work under 0.9.4(rel)
whereas the ones for OSS in the 2.4.20 kernel do work (ymfpci).

Is there still an oops?

Sorry, no oops, but doesn't work properly either.

What, exactly, does "doesn't work properly" mean? It doesn't compile?
"modprobe snd-ymfpci" fails? Error messages in /var/log/messages?
"aplay something.wav" crashes? The computer explodes? Green demons
coming out of your speakers?

:-)  oops.  Sorry about the vagueness...

"aplay something.wav" causes scratchy sounds to be emitted from the
speakers.

Not on my YMF-754 card. Sorry, I don't know what could cause this.

Ok, how can I help debug this?  (Albeit, slowly, as I am fairly busy)

If I remember correctly, the card is working with OSS drivers? Isn't?
In that case, we might compare PCI registers (lspci -s<DEV> -xxx).
