Hi All,

I am doing a routing test using linux 2.4 and linux 2.6 kernel on our
board. I am using 2.4.31 and for comparison.

I have ported the bsp and drivers from 2.4 to 2.6 and am using a
smartbits tester which pumps traffic at high rates and at varying
packet sizes.

On 2.4, the test goes fine ie I get meaningful values. But on 2.6
kernel, routing begins and continues for sometime before it completely
stops. The smartbits configuration is identical in both the cases.

I have noticed same problem with dlink and 3com cards which is causing
me to suspect that there is some probem with 2.6 routing.

Has anyone seen a similar problem ?
Any inputs on this would be appreciated.

Did you enable IRQBALANCE in 2.6?

$ zcat /proc/config.gz |grep IRQBALANCE

If so, please try to disable it.

Best regards,
