Subject: Re: Hardware Error Kernel Mini-Summit


The original motivation to put them somewhere else
because I was sick of people reporting them as kernel bugs.

But there's more to it now:

> If your system isn't broken correctable errors are rare.  People look

Actually the more memory you have the more common they are.
And the trend is to more and more memory.

Really to do anything useful with them you need trends
and automatic actions (like predictive page offlining)

A log isn't really a good format for that.
