To use cdrecord, you must have generic SCSI support, not just CDROM
SCSI support. Maybe this is missing from your new kernel. Regards
the IP-Config error, I think you have enabled bootp IP configs and
you dont have a bootp server. Do you have a .config file you can
send to this list? Normally called /usr/src/linux/.config
