System: FreeBSD 4.3-BETA: Sat Apr 7 17:06:39 CEST 2001
Machine: Siemens Mobile 510AGP Laptop with NeoMagic 256AV
>Description:
When using
device pci
device pcm
in the kernel config file, the machine hangs during booting when
initializing the NeoMagic 256AV sound hardware. It stops at the
indicated place of sys/dev/sound/pcm/mixer.c:
int
mixer_init(device_t dev, kobj_class_t cls, void *devinfo)
{
snddev_info *d;
snd_mixer *m;
u_int16_t v;
int i;
d = device_get_softc(dev);
m = (snd_mixer *)kobj_create(cls, M_MIXER, M_WAITOK | M_ZERO);
m->name = cls->name;
m->devinfo = devinfo;
/**** when executing the following line, the machine hangs ***/
if (MIXER_INIT(m))
goto bad;
/**** it never comes here ***/
for (i = 0; i < SOUND_MIXER_NRDEVICES; i++) {
v = snd_mixerdefaults[i];
mixer_set(m, i, v | (v << 8));
}
mixer_setrecsrc(m, SOUND_MASK_MIC);
d->mixer = m;
return 0;
bad: kobj_delete((kobj_t)m, M_MIXER);
return -1;
}
The machine works fine when 'device pci' is not present in the kernel
conf and the following pcm line is used:
device pcm0 at isa? port 0x530 irq 5 drq 1 flags 0x13
In this case some isa compatibility hardware is used. It also works
with the 'device pci' option when pcm had been left out of the
kernel config file (without sound, of course). For this latter case,
the dmesg is a follows:

>How-To-Repeat:
Use a Siemens M510AGP and boot a kernel that has pci and pcm stuff enabled.
>Fix:
Unknown. I will happily try out anything s.o. suggests.
