By "how well maintained" I meant "does someone actually fix them if
there's a known bug"?
I know that Redhat fixes them (or at least try to backport fixes),
which is why I use RHEL for production servers :D

I haven't had this problem with 2.6.18. It's either "all works well"
or traffic not going through at all (which was the case when there was
a bug in the NIC driver). There were also "eth0: received packet with
own address as source address", but nothing similar to the problem
that you mentioned.
Something to check though, are there any MAC-related message on
syslog? Is it possible that perhaps the MAC you're using is not
unique?
