Yes, it stops the crashes. If I set v6only = 0 then the machine
works normally; if set to 1 then I get connection refused from
any server I try to connect to. Is that normal v6only behavior?

Let's get this patch committed then. :)

Thank you for fixing it. I tried to fix as the same way as you did,
then during committing my fix, I found that it was already fixed by
you. :-)

Removing INET6 does stop the crashes.
After reading Scott Long's recent post I tried removing INET6 from my kernel config and the crashes due to mozilla are now definitely gone. The question remains, I suppose, whether there are other programs that will still trigger the same kernel bug in a different way, or whether the bug truly is in the INET6 code. I do know I was never trying to connect to any ipv6 site during the crashes, which seems a bit suspicious. If Seigo Tanimura's recent swapping patch also fixes the crashing (I haven't yet tried it) then perhaps the INET6 thing is just a red herring--but for now it seems okay to me.

Re: Removing INET6 does stop the crashes.
Yeah, removing INET6 seems to make it much more stable for me as well.
