Hi François,

I tried to apply your patches (against 2.6.27.2) but they failed. I am sending 
attached the rejects.

My previous report was a bit inaccurate. The network card failure are not 
constant, but random (something like 20% of the boots). Therefore It may be 
the case that this network card does not an updated driver because of this 
and because I disabled CONFIG_IRQBALANCE and the problem seems to be fixed 
now. (Does CONFIG_IRQBALANCE make sense with hyperthreading instead of a real 
smp?) I will continue to test and report if something happens. If I can help 
you with further testing, please contact me.

Best regards,
João Luis.
