[Asterisk-Users] zaprtc load issue (different that other postings)

[Spencer Nassar]

zaprtc 'load' is failing on my machine (the make was fine, same output 
as other posts to this list)
   [xxx at xxx zaptelrtc]# make load
   sync
   modprobe zaptel
   insmod ./zaprtc.o
   ./zaprtc.o: init_module: Input/output error
   Hint: insmod errors can be caused by incorrect module parameters, 
including invalid IO or IRQ parameters.
         You may find more information in syslog or the output from dmesg

I've seen other references to ensuring that rtc is unloaded first, but 
it's not loaded on my machine
   [xxx at xxx zaptelrtc]# lsmod

I'm running Redhat ES3 on a dual xeon system
Kernel is linux-2.4 -> linux-2.4.21-15.EL

Any ideas?

Thanks!
