Hi Michael,

thank you for the update, this is in fact really interesting. My recent tests 
were all done on x86. But i think, as 64 bit machines and distributions are 
getting more and more common, that this is not a general problem with openSER 
and 64 bit, but with the exact setup and distribution you use. Perhaps this 
is also a driver issue, as you mentioned.

Cheers,

Henning
