[hsflinux] Compiling hsfmodem with Kernel 2.6.13 impossible

[Linuxant support (Jonathan)]

Hi,

to be able to run the current version (7.18.00.05full) of the HSF modem 
driver on the 2.6.13 kernel, the patch named 
'hsf-7.18.00.05-simple_class.patch' is needed. On x86_64, the patch 
named 'hsf-7.18.00.05-errno.patch' is also required. These patches can 
be downloaded at:

http://www.linuxant.com/drivers/hsf/downloads-patches.php

It seems that you have hit a known crash issue with the HSF modem driver 
on x86_64 and we will contact you back when a fix will be available. 
There is currently no known workaround for this problem except to use a 
32-bit distribution of Linux.

Regards,
