Yeah I have been testing semi-regularly.

4.0-rc2 boots fine on mine.

But mine is an Athena, Steve's is an Electra. So they're not identical.

Mine is running:

  CFE version PAS-2.0.29 for ATHENA (64bit,MP,BE,PPC)
  Build Date: Mon Jun 30 11:47:25 PDT 2008 (mpl@mitch-1)

Steve is your CFE older than that?

Olof do you remember if that version or something newer is available for
Electra?

cheers
