[hsflinux] System freezes when browsing soon after dialout

Hi,

the x86_64/amd64/64-bit port of the driver is less mature than the 
x86/32-bit one and our developers are well aware of that. If we are able 
to reproduce the problem on our development systems, it will probably be 
solved in a future version of the driver.
