I'm just trying to put you in the user's shoes and make you take a
critical look at your error messages and ask yourself whether people
seeing this would know what's going on or not?

We've had the experience on x86 where people would have the *whole*
error message which would say, "error corrected, bla" and they still
would come and ask whether their hw is b0rked. We had to add stuff like:

	"Corrected error, no action required."

to let them know there was no affect on execution. And they'd still come
and ask. Even other kernel people! :-)

So please make sure your error messages are as understandable as
possible.

:-)

Thanks.
