MVME3100 boot failure at "Trying to find CSR on VME"

[Peter Linardakis via Tech-talk <tech-talk at aps.anl.gov>]

Hi all

Not a directly EPICS related question, but I'm at a loss.  We have a number of VME crates and one has started to misbehave after repair.

The MVME3100 successfully boots from the network but hangs before EPICS can start with the last line of the log being "Trying to find CSR on VME".  The result is the same for three different CPU cards, which all work fine when inserted into another backplane/crate.  The boot log is:

Does anyone have any ideas why a certain backplane will cause this?
