At boot time I get non-fatal error messages; the end of dmesg says
(full dmesg is attached):

I believe this was also in 4.8, but apparently persists in STABLE PRERELEASE as of yesterday.

My boot settings are as "out-of-the-box". Is this a problem in the kernel code?

Sorry, I'm not an expert at all on this; just found these error messages at boot time....
