It is warning you that your hardware is broken. Take it back to the
place from which you purchased it, and ask for your money back if it
isn't fixed.

(Slightly) more seriously, this level of warning *does* get things
fixed, and when kerneloops was running it made it very easy to track
this kind of issue and apply pressure where it was needed to improve
quality.

Any user who has taken the trouble to file bugs has *also* taken it up
with their firmware vendor, I hope?
