10Gb Eth Adapters - problem with data transmition
Hi, I have two Sun Fire v20 servers. On both, I installed 10Gb Ethernet PCI-X cards with Intel CB82597EX PCIX MAC controller and optical transceiver duplex LC Model No. 871879, XG-Base-SR. I have Suse Linux 9.3 (x86_64) OS with 2.6.11.4-21.9-smp kernel on both of them.
ethtool shows this:
Settings for eth0:

I had deinstalled ixgb module and installed ixge module. After connection those cards together the LED diodes on cards show connection and pings go well.
But I have problems with sending anything bigger then simple 64 bits ping! Even when I increase pings packetsize to let say 4000 bits, after a while the server which recives packetes automatically reboots itself.
Can you help me? what can be the reason of such behave?
Waiting for your reply, best regards,
Alex
