Re: Couple of questions

When I:
  insmod /tmp/enbd.ko

I get the following in dmesg:

   enbd: disagrees about version of symbol struct_module

nm of enbd.ko results in:

--snip--

                  U unregister_sysctl_table
                  U __up_wakeup
0000000000000000 r ____versions
                  U __wake_up

--snip

I can post the entire nm if it makes a difference, but after nm my other 
modules it looks similar. I don't see kernel versions on any of the 
other modules.

Ideas? Did I take a wrong turn somewhere?

Thanks in advancce again,

B
