Yep, it's in there: 7.6. My machine doesn't download the kernel when I try to netboot Your machine is replying to the BOOTP packets (you may verify this using a packet sniffer like tcpdump or ethereal), but doesn't download the kernel from your BOOTP server. This happens if your boot server is running a kernel of the 2.3 series or higher. The problem may be circumvented by doing a "echo 1 > /proc/sys/net/ipv4/ip_no_pmtu_disc" as root on your boot server.
