I use ramdisk-ext3 or NFS for my testing > Just to clarify, MMC suspend is not broken. It's a "feature" the MMC core. See the help text of the following Kconfig option, and ensure that it's enabled: config MMC_UNSAFE_RESUME bool "Assume MMC/SD cards are non-removable (DANGEROUS)" help If you say Y here, the MMC layer will assume that all cards stayed in their respective slots during the suspend. The normal behaviour is to remove them at suspend and redetecting them at resume. Breaking this assumption will in most cases result in data corruption. This option is usually just for embedded systems which use a MMC/SD card for rootfs. Most people should say N here. This option sets a default which can be overridden by the module parameter "removable=0" or "removable=1". Looking at Dave's .config, this option is disabled, so suspend will hang when rootfs is on MMC.
