10.0pt;font-family:Arial;color:navy'>I am presently using the Linux 2.6.19.2
kernel with I-Pipe real time extension (2.3.0) from the Xenomai project –
as bundled in ELDK 4.1 by DENX. I have also experimented with some newer
stuff, but this involves diving into the board support migration from arch/ppc
to arch/powerpc which is still pretty bleeding edge. 2.6.19.2 is pretty safe
and not too old – and is probably the newest available with RT option
while still being in the arch/ppc tree.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Don’t attempt to have buildroot automatically
build the kernel for you as part of its config – that may cause you grief
as their integration for PowerPC kernels appears hit-and-miss for 40x series
due to all the arch/ppc versus arch/powerpc stuff. Also, the buildroot
automatic kernel generation doesn’t include RT support (in case you need
it).<o:p></o:p></span></font></p>
