Hi,

Now I am a bit puzzled ;)

I rebuilt the rootfs against 4.14.x kernel headers, at least so I think ;)

bitbake -s | grep headers
linux-libc-headers :4.19-r0
nativesdk-linux-libc-headers                         :4.19-r0

... but still get the same syscall error:

root@multi-v7-ml:~# /usr/bin/smokey --run=16
[  448.996933] [Xenomai] bad syscall <0x197>
posix_mutex OK
root@multi-v7-ml:~#

0x197 is not present in a 4.19 kernel, so the error makes sense, but who calls it? It looks like something in the posix_mutex test triggers it.

Regards,

Robert
