Hi,
You may want to disable CONFIG_MAXSMP, some people reported similar
issues with this option enabled.

Here are kernel configurations files:
https://pastebin.com/zuucW3WW (for clean 4.9.90)
https://pastebin.com/AvD9T9Lx (for 4.9.90 with xenomai 3.0.7)
I have also checked if there is anything in /var/log/kern.log. Beside
normal kernel's logs there is nothing for the Xenomai flavoured version.
It seems about right because it is stuck at "Loading initial ramdisk".

I will post the kernel config file shortly and get back to you.
As for the prints, no, there is nothing only those two lines:
Loading Linux 4.9.90-xenomai-3.0.7 ...
Loading initial ramdisk ...

Posting the config may help. Can you get any early printks?

Hi!
I did additional test to rule out that Xenomai is the issue.
I have compiled kernel 4.9.90 without Xenomai and it turns out
that it
works. Having this in mind what could cause problem on Xenomai side?
If needed I will add additional information to trace the problem.
