As i will be an absolute newby here, i will not know how to get the stack trace out. When i will get some information how to get this, i can try to give you this information. But by my last tests i made the first 3 commands on an console and had no error. Only by typing the last line i will get the error and here i get actally only the "kern.err kernel: BUG: ....." message. Roland
