Hi Benjamin:

I forgot writing that I've sent the revised edition of
the patch to the PPC-Dev ML.
Please see the patch as ``boot time scheduling w hile atomic fix''
which I posted in 2005-03-15 from Patch tracking
system for PowerPC Linux as follows.

http://ozlabs.org/ppc32-patches/

It changes the implementation of kernel_thread function
to be performed with function call.

Regards,
