OK, why does this mean JFFS2 is guilty of this? Why don't you suspect your 
drivers? Why don't you suspect that you flashed your (say, correct) image

Just configure your kernel properly: switch on the "Test driver using RAM" 
(MTD_MTDRAM) option in your kernel configuration. Type "modprobe mtdram" 
if you have configured it as the kernel module.

If you do this your JFFS2 will work over emulated 4MiB in-RAM flash and 
this will help you to exclude driver problems.

HTH, Artem.
