Hi Antoni,<BR>
<BR>
The problem is LRO activated on bnx2x driver.<BR>
<BR>
After the reboot the LRO comes activated, after reconfiguring the bond the LRO is deactivated.<BR>
<BR>
So i created /etc/modprobe.d/bnx2x.conf with: options bnx2x disable_tpa=1<BR>
<BR>
and everythink is ok now after reboot.<BR>
<BR>
There was a previous bug open for RHEL5 about this problem <A HREF="https://bugzilla.redhat.com/show_bug.cgi?id=518531">https://bugzilla.redhat.com/show_bug.cgi?id=518531</A> should i reopen this for RHEL6?<BR>
<BR>
This problem only happens when bnx2x is used with bonds... should this be considered as a bug?<BR>
<BR>
Best regards,<BR>
Ricardo Esteves.<BR>
