Hi,
I have applied the adeos-ipipe-3.0.43-mx6q-1.18-14.patch provided with
xenomai-2.6.4 ,
onto the rel_imx_3.0.35_4.1.0 kernel

When CONFIG_IPIPE is enabled, the kernel is very slow to boot. Once it
is booted, it seems all right.
It boots fast when CONFIG_IPIPE is disabled

I have CONFIG_CPU_FREQ disabled.

It hangs for about 45 seconds after the
"console [tty0] enabled, bootconsole disabled" message

It is very slow to shutdown, too.

Where I can look to find the issue please ?

Best regards
Thierry
