So they're not identical. I have a chitra in my boot farm, so I run every build I do on it. I have not hit it either, which confused me. Turns out that Steven's machine boots with idle=doze, which is the part that makes all the difference. FWIW, the three machines have roughly these diffs: * Electra: First development/eval board. Funky USB on localbus, plenty of PCI-e. Two GigE, one 10GigE XAUI. CompactFlash and IDE on localbus too. Usually shipped with a PCI-e SATA card and a USB card. * Chitra: Second edition dev/eval board. Moved SATA and USB on-board, and removed some of the localbus hardware. Might have routed three GigE out instead of 2, can't remember. * Athena: Never released board with a smaller package chip, there's only a few of these around. Can't comment too much on the specifics, but it's similar to Chitra, and the silicon is the same. > 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? That looks about as new as they come. My board runs a .29 too. -Olof
