Subject: Re: Weird MMC errors: 2 of 2 - inconsistent state after data crc error

Problem 2: After a data crc error all subsequent commands fail. May it be caused by stop command
leaving card in some bad state (something clearable by SEND_STATUS)? On the other hand, is there a
real need to issue a stop command in case main command failed?
