Hi.
I am compiling for the Cobal Core with Xenomai 3.0.4 on Ubuntu 16.04
(kernel 4.4.0-77-generic).
When compiling the Linux kernel 4.4.43 with
ipipe-core-4.4.43-x86-6.patch I get the following error:
CC arch/x86/kernel/reboot.o

I've not seen any similar compiler issues on the mailing list and
since this patch have been out for 2 months, I'm wondering is it maybe
an Ubuntu specific issue?
On the same Architechture (Pentium-M) the previous combination worked
flawlessly nl.
xenomai-3.0.3
ipipe-core-4.1.18-x86-7.patch
linux-4.1.18
Any ideas?
Thanks
Michael
