this is a good sign :-)

it's probably a missing option in your .config if you started from the 
Debian version.

Can you try and apply all the options listed here:

https://github.com/thesofproject/kconfig/blob/master/sof-defconfig
https://github.com/thesofproject/kconfig/blob/master/mach-driver-defconfig
https://github.com/thesofproject/kconfig/blob/master/hdaudio-codecs-defconfig

Also it's probably better to use GitHub to attach information, etc,
https://github.com/thesofproject/linux/issues

also add the attached file as /etc/modprobe.d/sof-dyndbg.conf so report 
more info.
