I've seen this also few times, quite long time ago though.

Make sure you have patched the system to latest
available, then if that does not help or you have
already done it see if

- lsmod shows is the driver module still loaded?
  - if it is not you have at least two options

    a) add -k option to front of module name in /etc/modules.config
       (see man modules.config)

    b) prevent cron unloading the module, check /etc/cron*

  - if driver module is loaded, but your interface
    still does not work make sure you are not hit
    by PCI power-management, thus checking what you
    have in BIOS.

Sounds like the driver is unloaded to me. As usually
when you don't have the module you can't see nothing
with the ifconfig (if you haven't compiled the driver
statically to kernel).

BTW, this is not actually a Red Hat 7.2 tech-support
list, your question would have been more appropriate
at enigma-list or redhat-list.

A side note to Red Hat folks listening, it would be
possibly worth cosidering to add the list information
from https://listman.redhat.com/mailman/listinfo/ to
http://www.redhat.com/mailing-lists/ as it appears
that many have problems assosiating the release name
with the release number and directing the question
to right list.

HTH,
