Ben,
Thanks again for the tips. When my system is in multi-user mode, then I see
these device directories in the pci/drivers folder:
# ls /sys/bus/pci/drivers
3c59x VIA_IDE imsttfb pciback shpchp via686a
ENS1371 agpgart-via parport_pc pcieport-driver uhci_hcd vt596_smbus
#
However, when I go down to single user mode, my ENS1371 directory disappears.
So, I can't do the unbind at that point. Back in multi-user mode, I tried to
find out what else might be using this sound card, and found the following:
# lsmod | grep ens
snd_ens1371 30880 1
gameport 19464 1 snd_ens1371
snd_rawmidi 30848 2 snd_seq_midi,snd_ens1371
snd_ac97_codec 98592 1 snd_ens1371
snd_pcm 101124 3 snd_pcm_oss,snd_ens1371,snd_ac97_codec
snd 63492 12
snd_pcm_oss,snd_mixer_oss,snd_seq_midi,snd_seq,snd_ens1371,snd_rawmidi,snd_seq_device,snd_ac97_codec,snd_pcm,snd_timer
#
The next exercise in this set asks the student to prohibit the bind during boot
by editing the file /etc/modprobe.conf.local by adding the line:
#
options pciback hide=(0000:00:0b.0)
#
After this is done, I ran mkinitrd and rebooted. When the system came back up,
the driver was now available in the /sys/bus/pci/drivers/pciback directory. I
was then able to add the sound card to my virtual machine. So, this sounds
like the better approach. Still, it would be nice to figure out how to get the
highly advertised way to work, as well.
