ok after some playing a bit if i use

tc qdisc change dev bond0 parent 1: pfifo limit 30

the dropped packets go away, im not sure if that is considered normal or not, however any number under 30 gives me issues.
If there are no significant differences in configs between these 2.6.22
and 2.6.24/25 (e.g. things mentionned earlier by Eric) IMHO it's "more
than normal", but as I've written it would need a lot of your time and
work to check the rason.

BTW, it still doesn't have to mean any error: e.g. it could happen when
kernel throughput is better while NIC tx speed stayed the same. So, it
shouldn't probably bother you too much until there is no visible impact
on latency or rates.

Yes. I don't think this is an error, the configuration
was simply broken.
