ok, I added blacklist=mmc_block
to the end of my /etc/default/grub file then ran "sudo grub2-mkconfig -o /boot/grub2/grub.cfg" on rebooting I examined the grub commands and it showed the kernel was being booted with the blacklist option. This blacklist did not fix the problem. The card still is unrecognized after suspend. I removed the kernel option. I also tried adding "blacklist=mmc_block blacklist=mmc_core blacklist=rtsx_pci_sdmmc" to grub when booting with no effect. modinfo shows mmc_block and rtsx_pci_sdmmc both depend on mmc_core before suspend, as root, these commands attach and detach the SD card successfully: echo -n mmc0:aaaa > /sys/bus/mmc/drivers/mmcblk/bind echo -n mmc0:aaaa > /sys/bus/mmc/drivers/mmcblk/unbind After suspend, the above commands give the error "bash: echo: write error: No such device" before the first suspend: "sudo modprobe -r mmc_block" doesn't have much effect when the SD card is removed. This command resets the machine if the SD card is inserted and attached. after the first suspend: sudo modprobe -r mmc_block and sudo modprobe mmc_block don't seem to have any effect.
