user space probe in ubuntu 14.04

[Gareth]

Hey guys

What's the requirements for using systemtap in ubuntu 14.04 (kernel
version = 3.13)?

I have installed kernel-image package and found many probes by 'stap
-l 'kernel.function("acpi_*")'. However I sill can't use
process("xxx").xxx

I tried find online documents and I'm sure uprobe is enabled, utrace
is not. But that document said utrace is deprecated long time ago...

My output is here: http://paste.openstack.org/show/461444/
