I used the word "blacklist" but meant it only in context of suspends. Did you see the link? Check the bottom of that page. Instead of blacklisting the modules outright, try to rmmod then modprobe them (also per that page) and see if any get your SD working again. If so, add them to suspend-module-blacklist. Try these one at a time: mmc_block mmc_core rtsx_pci_sdmmc". -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
