Hmm, interesting image you sent!... I was curious about the image, so I had a look at it in my hex editor back home while waiting to get back into work tomorrow to actually test it. I was surprised to find the image to be repeating after 256kB, i.e comparing the first 256k with the second 256k showed they were identical! Is this what a LinuxBIOS romimage is supposed to be? If so, the images my builds have generated are certainly bogus, because I never got that. If not, could you have made an error when copying the image, so that your cluster nodes actually use this image in 256kB flashes?
Except for this, I couldn't see anything unusual.

no guarantees, but this might be it.
it's a 512KB image. What size rom do you have?

it's ancient. I had a build for 256KB, and only had a 512KB lying around, so I guess I did this: cat img img > img2

no
give it a shot.
You can also put an elfimage at the start of flash and leave the linuxbios at the end unchanged, i.e. use dd to cat off the last 64BK as the startup code, and then put different payloads at the front.
just an idea.
