Adam:

What does your romfs/lib/modules/2.6.28-rc2-ADI-2009R1-pre-svn5943/modules.dep

say?

Mine is:

./kernel/sound/blackfin/snd-ad1836.ko

loads both ./kernel/sound/core/snd-pcm.ko &./kernel/sound/core/snd.ko

My modules.dep shows:

/lib/modules//2.6.28-rc2-ADI-2009R1-pre-svn5952/kernel/sound/blackfin/snd-ad1836.ko:

/lib/modules//2.6.28-rc2-ADI-2009R1-pre-svn5952/kernel/sound/core/snd-pcm.ko

/lib/modules//2.6.28-rc2-ADI-2009R1-pre-svn5952/kernel/sound/core/snd.ko

But "modprobe snd-ad1836" fails.

It's ok on the revision 6001,but now modprobe needs /etc/modprobe.d other than

/etc/modprobe.conf.

Sorry for recommitting,I tested it with latest kernel and old uclinux-dist,

but after I updated uclinux-dist,the bug appeared.

Cliff means this bug is found after busybox update.

--- Mike Frysinger 2009-02-27 17:57:05

why do you think modprobe needs modprobe.d ? busybox's modprobe.c still works

with modprobe.conf and no modprobe.d ...

issue root caused and pushed upstream here:

lists.busybox.net/pipermail/busybox/2009-May/069173.html

--- Mike Frysinger 2009-05-05 20:23:14

the busybox depmod.pl needed updated ... should be fixed in trunk now
