I guess I've expressed myself in a poor way - sorry!

What I'm planning to do in the altera_edac notifier is:

if (kdump_is_set)
 return;

/* regular code */

In other words: if the kdump is set, this notifier will be effectively a
nop (although it's gonna be called).

Lemme know your thoughts Tony, if that makes sense.
Thanks,


Guilherme
