snmpd creating dirty buffers on a D-Link DFE-580TX

Hello list,

I use a quad ethernet card D-Link DFE-580TX in my server. As soon as I
start snmpd I get this in syslog:

kernel: 00 39d52000 00000000 00000000(00) 00000000 00000000
[snip bunch of messages like above]

kernel: cur_tx=3126(16) dirty_tx=3126(16)
kernel: cur_rx=20 dirty_rx=20
kernel: cur_task=3126
kernel: TxStatus=1500

kernel: cur_tx=0(00) dirty_tx=0(00)
kernel: cur_rx=0 dirty_rx=0 Dec 18 10:47:09
kernel: cur_task=0
kernel: TxStatus=0000

snmpd listens on 127.0.0.1. Distro is Debian Etch. The machine
has an unpatched vanilla kernel 2.6.23.11 (2.6.23.9 has the same
problem). These are the start options:

'-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid 127.0.0.1'

This is what I get in syslog when snmpd starts:

snmpd[4843]: could not open /proc/net/if_inet6
snmpd[4843]: cache has existing timer id.  Dec 18 10:46:40
snmpd[4843]: NET-SNMP version 5.2.3 

Anyone a hint? Maybe this is not an snmpd problem at all, but I have to
start somewhere...

R.
