illegal intruction

[Pawel Zawora]

I'm working with Linux PPC, kernel version 2.2.13 with nfs as a root
file  system. When I try to run any software sometimes a exeption
undefined instruction code 0xffffffda occurs (kernel try it emulate),
sometimes everything works.
Does anybody know what can be a reason of  behavior like this?
It isn't a problem of limited RAM memory space.
What is  the best way to find this error?
