EBUSY isn't used so much in the driver code, so I wonder how it can
get.  Could you rebuild with CONFIG_SND_DEBUG_VERBOSE=y and check more
messages?

Also load snd-hda-intel module with probe_only=1 option.
This will initialize the codec without parsing, so that you can still
get the codec info.  Run alsa-info.sh (with --no-upload option) and
attach the output for further analysis.


thanks,

Takashi
