Re: Hsfmodem and extra RAM making Linux frreze....

Hi,

please try with the default kernel shipped with the Linux distribution 
you are using. If the driver does work correctly (with > 1GB RAM), build 
your own kernel with only a single change from the default kernel and 
test again. Keep adding kernel options and kernel patches to finally 
reach the kernel you want. Each time you add an option or patch, you 
should build a new kernel and test the driver again. Eventually, you 
will find out which specific kernel option or patch that is incompatible 
with the driver with > 1GB RAM.

You should also try with the latest versions of the HSF driver and 
alsa-driver-linuxant as well.
