This bug has been fixed since Hardy, I think it was accidentally left open because it was marked fixed in Debian, but not in Ubuntu.
Let me reiterate that this bug applies specifically to a DHCP protocol violation in klibc, and was fixed in the beginning of 2008, in time for Hardy. Any other problems that may cause network-related kernel panics on boot in LTSP are not related to this bug.
