GCC4 fun.

I have seen it since 2.6.11-rc2

It is not a fatal error, just more of a warning.
It complains because schedule() was called while scheduling is disabled
during initial setup

As far as I have been able to track it down, schedule gets called after
syscalls, and in this case (and in mine on a 8260)
It gets called when the proc filesystem is enabled.

These errors surfaced on PPC after Ingo Molnars patches to get rid of
the BKL (Big Kernel Lock)
