Claudius, I am running into similar issues with linux-yocto-rt.  I am working 
out of poky/krogoth.

I have the following two lines set at the end of  local.conf

COMPATIBLE_MACHINE_genericx86 = "genericx86"
PREFERRED_PROVIDER_virtual/kernel = "linux-yocto-rt"

I also have MACHINE ?= "genericx86"  which I think should be sufficient for a 
32bit build.
SDKMACHINE ?= "i686" as well for the SDK.

I have been unable to obtain a build.  I have no idea what else needs to be 
set.  If you figure it out let me know.

Subject: [EXTERNAL] [yocto] [meta-intel][Galileo] Kernel configuration isn't 
applied on linux-yocto-rt


I am currently trying to compile the linux-yocto-rt kernel for a custom board 
(called iot2000 here) based on the Intel Galileo platform.

The build fails, because the kernel configuration isn't applied.

However, the bitbake environment of the linux-yocto-rt target looks good to me 
and everything works when I switch to the linux-yocto kernel, where the same 
configuration is applied.

Any help would be appreciated.

Thanks, and have a nice day,
Claudius Heine
