i have never seen a card properly recovering after a firmware crash, all 
firmware crashes i have seen
are caused by bugs in firmware handling or the firmware itself. so if it 
recovers it crashes immediatly again
ending in a endless crashloop since the cause for the crash hasnt been 
fixed. they are often triggered by extern clients for instance which 
still remain in the field.
i think firmware crashes should not be hidden by recovering. this would 
also force users to report problems more frequently, than they do
since they dont even take notice of such problems
