@ed_boner
because Mohammed muid mentioned that
i bet you haven't try before installing sp

it is bloody confirmed that the reboot problem is caused by KP
why don't u try booting normal kernel (OMAP) and see your self that the reboot problem from xterm is solved

@sophocha
it's known that you have to reboot twice after installing sp

first one will remove everything from /syspart
second one is to place create /dev/cgroup

the first one usually gets laggy N900
but the second and the rest are all smooth
