unresolved emu10k1 synth symbols.

unresolved emu10k1 synth symbols.

[Dave Jones]

I just noticed this whilst booting 2.6.16 on a test box

snd_emu10k1_synth: Unknown symbol snd_emu10k1_ptr_read
snd_emu10k1_synth: Unknown symbol snd_emu10k1_synth_copy_from_user
snd_emu10k1_synth: Unknown symbol snd_emu10k1_voice_free
snd_emu10k1_synth: Unknown symbol snd_emu10k1_synth_free
snd_emu10k1_synth: Unknown symbol snd_emu10k1_ptr_write
snd_emu10k1_synth: Unknown symbol snd_emu10k1_synth_bzero
snd_emu10k1_synth: Unknown symbol snd_emu10k1_voice_alloc
snd_emu10k1_synth: Unknown symbol snd_emu10k1_memblk_map
snd_emu10k1_synth: Unknown symbol snd_emu10k1_synth_alloc

This kernel was configured with CONFIG_SND_EMU10K1=m
and CONFIG_SND_SEQUENCER=m

This looks like it can't possibly work, unless I change
CONFIG_SND_EMU10K1 to =y.  Is exporting a symbol from one
module to another actually supposed to work?
I thought this was why we had the ill-fated intermodule_register() ?.

How could e.g. CONFIG_SCSI=m or CONFIG_USB=m do anything useful if it 
wasn't?

Weird.  By modprobe, snd-emu10k1 module should be loaded in prior to 
snd-emu10k1-synth because of the dependency of above symbols.

How is snd-emu10k1-synth module loaded?

with the following modprobe.conf fragment

install snd-emu10k1 /sbin/modprobe --ignore-install snd-emu10k1 && /sbin/modprobe snd-emu10k1-synth

Does the manual modprobe snd-emu10k1-synth after loading snd-emu10k1
work?

Isn't that command wrong ?
You are telling it to ignore the install for snd-emu10k1.
How about :
install snd-emu10k1-synth /sbin/modprobe snd-emu10k1 && /sbin/modprobe 
--ignore-install snd-emu10k1-synth
