My MMCplus cards run at the same speed with either > controller. I too confirm that. However that suspend/resume race is tough one. The problem seems that controller doesn't like both devices to be poked at same time, and normally they won't, but here on resume both are tested for a card, and this is done asynchronously by mmc core. I will get to bottom of this sooner or later (I hope). Best regards, Maxim Levitsky
