I've seen a block of ports on an older 10/100 linecard drop; recovery 
came at next reboot.  I've seen a 10/100 card die, and force a reload as 
it went down.  Sup720s have been good to me.  I think I've seen 1 or 2 
backup Sups hiccup but come back to life.

More recently as a consultant, a customer's DC is showing one completely 
dead Sup (which forced an SSO event), one backup Sup that reloaded; out 
of ten units.
