Hi

When I run the linux kernel you sent with

--ide-master klibc-rootfs.img

linux boot to busy box and I can run 'ls' for example

but when I run with the other image

--ide-master bb-rootfs.img

it also boots to busy box, but running 'ls' or any command gives a 
'segmentation fault'

do you know why ? what's the difference between these 2 img ?

Is that what you mean with "User-space programs crash when data-cache 
emulation is enabled" or is this another scenario ?
