pcm sound driver crashes at boot time.

1999-04-19 Thread Russell Cattelan 
I haven't been able to track down exactly where this
is occuring, but disabling pcm allows eliminates the crash.

The build is current as of Sun 18th.

The one strange thing about this box, it has 
two sounds cards. A build in Yamaha OPL-3 (really really crappy)
and Ensoniq AudioPCI 1371 (very hacked driver, So the problem may be my fault).
But I guessing it has more to do with the newbus stuff.

Ok I finally tracked down what was going wrong, I'm not saying I found the 
problem
of how to fix it correctly.
The cause:
pcmprobe gets called after es_pci_attach (which has setup the snddev_info 
structure),
the first thing pcmprobe does is bzero that structure. Which of course cause a 
page fault
the next time that structure is access. (by es_intr in this case)

The really QD fix was to just return from pcmprobe.


int
pcmprobe(struct isa_device * dev)
{
  DEB(printf(pcmprobe dev:0x%x name:%s\n,dev,
(pcm_info[dev-id_unit]).name));
  /* The AudioPCI probe stuff was done already */
  if(!(strncmp ((pcm_info[dev-id_unit]).name,
ES1371,strlen(ES1371{
 return 1;
  }
bzero(pcm_info[dev-id_unit], sizeof(pcm_info[dev-id_unit]) );
return generic_snd_probe(dev, pcm_devslist, pcm) ? 1 : 0 ;
}
