hi everybody. im using tftp - hpa running on Debian (Sarge) GNU Linux. my problem is about 2 clients when getting same kernel image at same time ! this thing happens in my home, but same system works at my work. when i want to boot up 2 clients via network i see boot message and then they crashes and give an error message ; Unable to mount root .... kernel panic ! ... my both switches allows to pass the udp packets, there is not packet filtering, discarding or blocking. Thanks.
