How to clear all error events retained by FMA?

Hi,

I've been exercising with zpools for a while, corrupting with dd, failing devices and so on.
Now I'm done, all pools are healthy but I realize there's a lot of error events still present in FMA (fmadm faulty).
I've tried "fmadm repaired" and other options but with none of these options I can get rid of the error events.

Is there a way to get rid of them?
(preferably not rebooting, of course, if that would be a solution anyway)

Thanks in advance,
Carlos.
