Hi all, Looks like commit e63201f19438 ("mmc: omap_hsmmc: Delete platform data GPIO CD and WP") caused mmcblk0 to stop being detected on boot on some omaps. According to Aaro and Adam, mmcblk0 does get detected after replugging the SD card. Reverting the commit fixes the issue. Any ideas what might be causing this on boot? Are we maybe missing a call on boot to mmc_gpio_get_cd() somewhere? Regards, Tony
