The mmc card is then used by another processor without linux. That works very well. My question is, why i get always the message "mmc_host mmc0: WARNING: IMR=0x00004040" after i removed the mmc card slot once. That's a new behavior with 3.2.1. I had no message with 2.6.35.3. When the mmc slot returns to linux, the message stops and i get: mmc_host mmc0: WARNING: IMR=0x00004040 mmc0: host does not support reading read-only switch. assuming write-enable. mmc0: new SD card at address b368 mmcblk0: mmc0:b368 H1697 1.91 GiB mmcblk0: unknown partition table That's fine. Should i just ignore the message (or simple patch driver/mmc/host/atmel_mci.c)? TIA Tom
