Hello, we know this : it is udhcp which causes the problem. I try to translate:
The option DHCP 61 (clientid) is empty in the configuration. You must supress the -c option in: /usr/share/initramfs-tools/scripts/init-premount/udhcp (otherwise our cisco router used to filter the dhcp packets comming from th thinclient.) Yours t.d.
