Dave you touch core of problems .. messages occures constantly but high
network activity occures only at night on this interface (backup). In
attachment is weekly graph network acivity measured on SNMP agent on switch
on this port.
At day usualaly on this interface activity is is very low (5-40Kb/s in/out).
In attachemnt is filtered kernel log with timestamps which shows all
"eth0: Happy Meal .." and "hw tcp/udp v4 csum failed" which was occure
after yesterday boot on kernel 2.6.13-1.1552sp1 (which bases on
2.6.14-rc1).
Backup was between 1:00 am and 4:00 am.
As you see there is no corelation between messages and high/low network
activity.
