Problem booting kernel on EP405

[Phill Treddenick]

Hi,
  I am trying to run Monta Vista Linux PE 2.1 on an EP405 with Solaris 2.7 as
the host.  When I boot the kernel on the EP405 though, I get a couple of boot
error messages.  The kernel continues booting however and gets to a login
prompt, if I try to login though it fails.  Can anyone provide me with
information about the errors I'm getting.  Specifically, the "modprobe:
modprobe: Can't locate module char-major-4" and the "mknod: `/dev/ptmx':
Operation not permitted" errors.  I would like to know where I would find the
char-major-4 module or why the kernel can't find it.  Here are the boot messages
and a failed login attempt. Thanks guys.
