	I've seen the problem Rich has described on at least a 
dozen m160s.  After offlining the SFM due to bad memory, at some
later date/time, it would return to an online state, and start causing
packet corruption problems or similar, again.

	At one point, we had an expect script running that would 
login and alert us to this condition when it recurred.

	The only fix we came up with was to have a tech onsite pull
