[Xenomai] kernel does not boot when ipipe tracer is activated

[Cédric Perles]

Hi,

I’m working on an iMX6 based board with NXP kernel 4.1.15.
Using cyclictest and dohell, I benched latency on my Xenomai + Preempt-rt
kernel. To understand the results, I wanted to activate ftrace and
ipipe-tracer.

While ftrace activation was not a big deal, when "I-pipe debugging" is
activated into menuconfig my kernel does not boot anymore and hangs to
"Starting kernel ..."

Did someone faced the same issue ?
Is there a way to investigate

Regards,

Cédric.
