Hi, The mmc subsys has a Kconfig option which more or less mirrors CONFIG_USB_DEFAULT_PERSIST, which Fedora enables. I would like to suggest to enable the MMC variant too, without this on suspend / resume, the kernel will assume that the card was swapped by one which happens to be of exactly the same type, thus forcing an unmount off any fs which was on it and killing any apps which happen to have files open on the device. For ARM where the rootfs often is on an sdcard this is disastrous, but one PC-s it is not really userfriendly to kill any fs on an sdcard on suspend / resume either. Therefor I would like to suggest that we start enabling CONFIG_MMC_UNSAFE_RESUME just like we do for CONFIG_USB_DEFAULT_PERSIST, note that despite the "scary" naming they are in essence pretty much the same, assume if the same device is still present after suspend / resume, that it really is the same device even though we cannot be 100.1 % sure.
