ok - issue solved - the following made it work: swapon /dev/mmcblk0p3 insmod /lib/modules/current/ramzswap.ko disksize_kb=65536 swapon /dev/ramzswap0 -p 10 swapoff /dev/mmcblk0p3 it seems that enabling the internal memory's swap was needed to avoid the crash - i don't know why. Now i have 2 swaps: /dev/mmcblk1p4 (P -1) /dev/ramzswap0 (P - 10) Thanks for the help.
