Sorry, forgot to attach the patch file. Thanks Arnd for the input. I've prepared a RFC-Version of the patch. I'm not quite happy calling mmc_sd_resume() from the rescan ioctl. Unfortunately the rescan needed it twofold: 1. Force the SD layer to reread scr, ssr, etc. by somehow reaching mmc_sd_setup_card() 2. Remove GENHD_FL_NO_PART_SCAN from the disks flags and trigger a ioctl BLKRRPART on the block device. Which I would prefer to happen within the kernel. Either one should introduce a flag in the mmc_card struct that forces a rescan of the sd card or even remove it completely and probe it again. Or there should be a command like mmc_card_reinit() which restarts mmc_sd_setup_card() along the way. What is your opinion? Regards, Peter
