Dear Linux folks,


With Linux 4.15-rc2 built by the Ubuntu Kernel Team, the error messages 
below are shown by the Linux kernel. These are new.

```

Any idea what to do about those? If these are intentional, it’d be great 
to give some hint to the user, what effect this has.


Kind regards,

Paul
