Package: src:linux
Version: 4.9.2-2
Severity: normal



Dear Maintainer,

This was a clean Debian Strech installation (one of the January weekly builds with linux-image-4.8.0-2-amd64) - the error was there from
the beginning. After "dist-upgrade" nothing changed with new linux-image-4.9.0-1-amd64. 
It seems that everything works normally but "dmesg" output (attached at the end of this bug report) filled with warnings.
 
Additional information can be provided if needed.
Thanks.
