System Hangs After GRUB Menu Entry is Selected

If the client is able to do the initial boot but the kernel cannot be booted, the system freezes (or hangs) after you select the entry from the GRUB menu.

On the AI server, check whether the grub.cfg file or the menu.lst file for this client is pointing to a valid boot archive. The boot directory of the image on the AI server should be loopback-mounted under the /etc/netboot directory as shown in this sample excerpt from df -k for the image path shown by installadm list:
