[hsflinux] [BUG] hsfmodem-7.47.00.01: hangup, deadlock?

[Linuxant support (Jonathan)]

Hi,

the protection is unlikely the source of the problem and the driver 
should not crash even if a program asks to use a modulation which is not 
available with no license installed.

I have attached to this post an experimental patch for the devfs problem 
you have mentioned. This patch is needed to be able to use the driver on 
2.6.18-rc1 or later kernels. It can be installed with the 'hsfconfig 
--patch <file.patch>' command in a root shell.

Regards,
