"kernel panic - not sync: unable to kill init", the real message comes
before, and generally the most important error message is the first one.

First, to see if the problems comes or not from Xenomai, I advise to
compile a kernel without Xenomai and I-pipe support first.

If you still have a problem without Xenomai and I-pipe support, then I
am afraid you are writing to the wrong list: we know how to compile
Linux, but not every specific detail about every IDE controller.

Now, from what I read in the kernel configuration, it seems that the
kernel has no support for SATA controllers for Geode. The only
controllers for Geode I see are:
- In the ATA/ATAPI/MFM/RLL support menu:
  . AMD CS5535 chipset support
- In the Serial ATA (prod) and Parallel ATA (experimental) drivers menu:
  . CS5510/5520 PATA support

All of them PATA controllers. I do not really know if PATA drivers in
the "experimental" menu appear as /dev/sda or /dev/hda, but you may try
this. And in any case, the boot logs should help you (when the IDE
controller is correctly configured, you should see messages about the
IDE disks detected and their name).
