So curiosity got the better of this cat, as to why we are not seeing
this ;-)
The main difference I see between the tegra_defconfig and
multi_v7_defconfig is all the sound drivers are modules (including
this one).
So trying a quick modprobe of the hda-tegra driver I do see it hang ...
/ # modprobe snd-hda-tegra

Adding some debug it appears to hang on snd-hda-codec-hdmi (the following show
the order in which modules are being loaded) ...
/ # modprobe snd-hda-tegra
[ 22.450276] snd_hda_tegra: err = -2
[ 22.484535] soundcore: err = 0
[ 22.488964] snd: err = 0
[ 22.493242] snd_timer: err = 0
[ 22.498380] snd_pcm: err = 0
[ 22.502479] snd_hda_core: err = 0
[ 22.508337] snd_hda_codec: err = 0
[ 22.513386] snd_hda_tegra: err = 0
[ 22.740216] snd_hda_codec_hdmi: err = 0
[hangs here]
However, if I do the following, this works ...
/ # modprobe snd-hda-codec-hdmi
/ # modprobe snd-hda-tegra
So it implies that snd-hda-codec-hdmi needs to be loaded first otherwise it hangs.
Thierry, any thoughts?
Jon
