as you have mentioned, it is quite possible that all the issues you have 
reported are directly related to the fact that you are using a 4K stacks 
kernel and the HSF driver can requires more than that.

We offer a pre-compiled RPM of a Fedora Core 4 kernel with 16K stacks as 
a convenience for our users. You can obtain these kernels at:

i586: http://www.linuxant.com/drivers/hsf/full/downloads-fc4-kernel-i586.php
i686: http://www.linuxant.com/drivers/hsf/full/downloads-fc4-kernel-i686.php

Then, install the kernel and reboot in this new kernel. Finally download 
and install the HSF driver package for this new kernel version. You can 
also obtain it from the HSF driver download page at:
