i've got a very strange problem using ZFD 6.5.1

I restore image on some IBM Intellistation M PRO. Everythings works fine
but on two of them img load and crash immediately. (zisedit and zisview
work) I try the latest imaging kernel from Novell Forge but it is the same.

Does anyone encounter this kind of problem ?
Did someone got an idea ?

Thanks for help
