Function Profiler broken on today's linux-next

Hi folks,
I was trying to use Kernel Function Profiler to figure out why my
driver's IRQ handler is taking so much CPU time but to my surprise,
whenever I try to trace anything, I get a "Unable to handle kernel
paging request at virtual address XXXX" error.
Is anybody else seen that or did I screw up my Kernel config ?
cheers
ps: I have tried tracing a few different drivers and they all trigger
the same problem.
