Hi EveryOne,

   I am new to Xenomai , I have ported linux-2.6.14 to our custom board
based on IBM750Cxe Iam unable to boot my kernel cross compiled with eldk-3.0with
   enabled xenomai support.If i remove xenomai and ipipe support the kernel
boots correctly , but if i enable CONFIG_IPIPE I get stuck in the before
mounting the root file system  .

   The following patches are applied and arguements of scripts/prepare-
   kernel.sh is mentioned as follows
   adeos-ipipe-2.6.14-ppc-1.3-05.patch,
