You can safely ignore the modprobe message.. it's not an error bug really a warning. Now for the other issue.. the mknod error and the unable to login.. See below: > IP-Config: Complete: > device=eth0, addr=128.138.189.65, mask=255.255.255.0, gw=255.255.255.255, > host=sme, domain=, nis-domain=colorado.edu, > bootserver=128.138.189.51, rootserver=128.138.189.51, rootpath= > VFS: Mounted root (nfs filesystem). > mknod: `/dev/ptmx': Operation not permitted > login[82]: unable to change tty `/dev/console' for user `root' > > Unable to change tty /dev/console: Illegal seek The above shows that you are NFS rooted. On your NFS root, it was unable to mknod /dev/ptmx. Either you have a RO NFS export on your slowlaris box, or somehow you are exporting a system in which you are unable to create device nodes. /dev/ptmx is required for the multi-user login to work. It controls the PTYs. The second error if that it is unable to change the tty for /dev/console to root. This again indicates that there is a problem with device nodes over your NFS mount. Make sure the NFS mount is RW. --Mark ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
