If I do reboot it comes back ok. I have tried it on two different platforms 1) a Biostar TForce 6100 mainboard with an AMD dual core processor 2) a Soekris net5501 with the same results. I get the dumping message and then it hangs and I have to hard reset the box. Thanks, Steve -- "They that give up essential liberty to obtain temporary safety, deserve neither liberty nor safety."
