Hi I backported the changes for r8169 2.6.33 driver to 2.6.32 to see if it would resolve this problem but the same error still is present.<div><br></div><div>However, if I use an 8139too card with 2.6.32 driver there are no errors.</div>
<meta http-equiv="content-type" content="text/html; charset=utf-8"><meta http-equiv="content-type" content="text/html; charset=utf-8"><div><br></div><div>Any ideas for fixing this for the r8169?</div><div><br></div><div>Thanks again,</div>

This may be a buffering problem of the used network adapter. Maybe it<br>
can not store three frames before you fetch them from the hardware.<br>
Splitting into more domains will not be helpful, if this is the case,<br>
because the width of the process data keeps the same. Do you have the<br>
possibility to try a different network adapter?<br>
