Hi,
(Xenomai 2.5.2, Linux 2.6.33, PowerPC)
I noticed the following behaviour in the prepare_kernel.sh script.
When using target name "powerpc" all is fine, but when using "ppc" the
script hangs after patching all files.
Strace indicate the script hangs waiting for an entry (probably a file
not found and a grep or other tool wait on the stdin). Strace output
is at the end of this email.

Is ppc a correct target name ? In the prepare_kernel.sh script the
variable $linux_arch seams to have a different value when using ppc.
arch/ppc directory does not exists in Linux 2.6.33 sources.
   ppc|ppc32)
      linux_arch=ppc
      xenomai_arch=powerpc
      ;;
   ppc64|powerpc64)
      linux_arch=ppc64
      xenomai_arch=powerpc
      ;;
   powerpc)
      linux_arch=powerpc
      xenomai_arch=powerpc
      ;;




Strace output :
