cramfs: wrong magic ??

[toko]

Hi,

on my MD (HP ThinClient used as diskless device) when I switch to a terminal session the system automatically keeps typing "cramfs: wrong magic" all the time. Found no information about such an issue here or in another linux forum. So far it says that when it is displayed once during boot it can be ignored. But in my case I cannot type even user name and password without having typed those error messages automatically into between.

what does this message mean? it the harddisc having failures? or can it be hardware incompatibility with the ThinClient? However the station works so far, although it sometimes simply hangs and has to be restarted....
