Hello all,

While attempting to install the HSF modem driver on a Fedora-based system, i receive the following output while loading the modules :

[root at test hsfmodem-]# hsfconfig
Conexant HSF softmodem driver, version

If you need license keys, assistance or more information, please go to:

When reporting a problem for the first time, please send
us the file generated by "hsfconfig --dumpdiag".

No pre-built modules for: Fedora-8 linux- 

Trying to automatically build the driver modules...
(this requires a C compiler and proper kernel sources to be installed)

Where is the linux source build directory that matches your running kernel?

Building modules for kernel, using source 
/lib/modules/ Please wait...

Warning: no device detected by hsf driver - HDA modems may require reboot

Note: HDA support not compiled in the driver
[root at test hsfmodem-]#

The compilation appears to complete successfully, in that the modules 
exist ; however, both at compile time, as well as at boot, the same Oops 
message is displayed.  An lsmod shows that the modules have been loaded 
into memory, and /dev/modem is created as expected, but actual 
communication with the modem is not possible (via minicom, for example).

I am more than happy to provide any other additional output upon 
request.  Thank you for your time and consideration.
