Sorry for the missing history. I started with a vanilla 2.6.14-7 kernel from kernel.org, I patched it with a Motorola patch to enable the features specific to the mvme5500. I built under ELDK 4.0 and the kernel ran just fine.
Next I retrieved xenomai-2.1.1 and followed the install instructions. The adeos version adeos-ipipe-2.6.14-1.2.03.patch. This patch applied and I rebuilt the kernel. I ran into a problem with xmon not compiling so I removed that switch from the kernel hacking menu and it built fine. That brings us to now. In reference to your recommendation, can I simply disable ipipe and leave xenomai enabled and expect the kernel to run? I thought there was a pretty close coupling between the two. Thanks for the help.

If the bug seems to be ipipe/xeno-related, please report the patch and the xenomai versions, and also any potential board-specific patches.
