I think the problem is that when the device mounts the MMC during the boot process, metalayer-crawler gets inotified about that and starts scanning the contents of the MMC. Metalayer-crawler didn't handle possible errors from corrupted (MMC FAT) filesystems well enough and as a result it in worst case ended up up taking all memory and CPU in the device. This is fixed in the next release. It should also now react properly/promptly to user removing the MMC. There might also have been problems with some specific video files. What was the format of the video files which removing helped? - Eero
