with the information you have provided, it's quite possible that the 
source of the problem is that there is an important issue when you 
remove the modules from the kernel for an unknown reason.

You could try with a newer kernel to see if there is a difference.

Alternatively, as a workaround, since the ability of removing the 
modules from the kernel is only required to install a license, you could 
edit the '/usr/sbin/hsfstop' script to prevent it from unloading the 
kernel modules.
