The status of kernel tasks should not be new or incomplete when submitting for
SRU. And we should set an importance. For non-essential functionality impaired
this is medium. I would use medium in most cases, high only for essential
functionality impaired and critical for things that put ones data at risk. That
is for the kernel tasks, other teams view can be different.

Should be [Regression Potential]

Only if the same vendor/model numbers were re-used by hw that needs a different
setup, the microphone might stop working there.
