ERROR: alt2 does not exist in /proc/modules

ls /proc/modules
<empty>

>3.  modprobe atl2

FATAL: Module alt2 not found

Wow.  /proc/modules are empty???  Is that significant?

I checked the /lib/modules/<kernel-version>/kernel/drivers/net
and in there are:

atl1/
 atl.ko
atl2/
 atl2.ko

So they are there as before.

Thanks-
