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:

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.
