This is an old cranky Adeos/I-pipe patch with a silly glitch in it,
disabling CONFIG_PARAVIRT should help. Normally, you should be able to
pick the latest 2.4.x official release (2.4.10) instead of 2.4.3. All
releases within a major series are guaranteed to be API and ABI backward
compatible.

In any case, unless the code generator itself has (weird) kernel
dependencies, you don't need to stick with 2.6.24 for Xenomai 2.4.x to
work, you may upgrade up to 2.6.30.8 with Xenomai 2.4.10.

I did not know this generator existed, so ...
