Which radvd version are you running?  In radvd, there were changes to 
this, and it should reactivate the interfaces when they're back. 
Setting "IgnoreIfMissing on;" additionally quences some error 
messages.  Prior to 1.0, IgnoreIfMissing might have brought you 
what you were looking for.

If this is the case in recent radvd version, sending radvd debug 
output (e.g. radvd -d 5 -m stderr) could help.
