Finally decided to test with AA (kernel 3.3.8) for which i've made a
some kind of patch to enable SMP and nothing strange with jffs2 fs
happened.
Also noticed that bogomips in core 1 are the same that in core 0,
while with BB they are different:

http://pastebin.com/KieR005R
Of course a difference in bogomips does not mean nothing.

Attached is the patch; i've made it with the patches that Jonas, Kevin
and Florian have sent to linux-mips and openwrt.

Still i have no idea where is the problem, but hope that this info
could help others to find what is happening.

José Vázquez
