Sorry, I don't either. Some random comments follow. > What happens is this: > The clients boots via Etherboot, which then loads a kernel using > tftp-hpa.

For a client not to be able to boot the kernel, one might think that the kernel it got was corrupted on some way. But why would that correspond to the uptime on the server?

The "Ok. booting the kernel..." message indicates a problem with the kernel. Make sure the same kernel is given the clients each time. Are the clients are powered down between boots? I use tftpd on Debian Woody rather than tftpd-hpa, so I can't comment on that one. -- Hans Ekbrand
