Hi,
I tried to blacklist the crashing module (snd_soc_rl6347a) without any 
success: it still loads. I booted kernel with 
modprobe.blacklist=snd_soc_rl6347a and I put "blacklist snd_soc_rl6347a" in 
/etc/modprobe.d/blacklist.conf. I even tried to recompile the kernel 
without that module, but there is no option in "make nconfig" to disable 
it, while adding "# CONFIG_SND_SOC_RL6347A is not set" to the config 
doesn't help because it keeps showing CONFIG_SND_SOC_RL6347A=m in "make 
nconfig" if I search for it with F8.
I attached another log with modprobe.blacklist=snd_soc_rl6347a plus 
modprobe.d entries: https://bugzilla.kernel.org/attachment.cgi?id=189361

Thanks,
Niccolò Belli
