No, IPv6 is just some kind of luxury. The majority of work is done via
IPv4. It is just easier to make the box accessible from the outside
via IPv6 since it's IPv4 connectivity is natted.

I will try doing so. At the moment, I am pretty much traveling five
days a week and do not have much opportunity to use the wired
Ethernet, but I haven't seen the crashes recently. So it might as well
be fixed in 2.6.35.4.

I will do that as soon as I see the issue again.
