Is the spu scheduler a module that doesn't exist in the
vmlinux proper? If you run "gdb vmlinux" alone, and
enter "ptype struct spu_prio_array", does it know what
it is?
If it is a module, then its debuginfo data will have to
be loaded with the "mod" command.

Thanks a bunch, Dave,
It's in the spufs module. You are correct, I had to load
the module before loading the extension:
mod -s spufs
I hadn't noticed it before because it was not happening.
