It looks like run out of memory. The DE2 has only 8M sdram. 

Try remove used file in ~/rootfs, remove unused devices in ~/download/rootfs_list, disable unused options in kernel, disable used options in busybox, use jffs2 on cfi mtd to store files or rootfs... all that help to reduce memory usage.

You have to edit drivers/mtd/maps/alters.c .
