Hi
Periodically (initially I thought it was related to bgfsck) but
I've just had the problem again after 6 days of uptime with no
provocation.
I get massive packet loss and out of order delivery as evidenced below.

I'm running vlans and carp with polling on top of this.
This is the builtin NIC on a Del R905.
