Nivedita Singhvi wrote: Rob Gardner wrote:The machine with the problem: Intel e100 nic 1.7 Ghz XeonYep, practically all instances of this problem were with the e100. Unfortunately, the current version of the driver no longer has NAPI as a dynamically tunable parameter via ethtool. It can be disabled via a kernel config parameter (CONFIG_E100_NAPI). You could recompile and see if the problem disappears. (Not a real fix). My current configuration has: # CONFIG_E100_NAPI is not set Isn't that the same as it being disabled? Or should I change it to: CONFIG_E100_NAPI=n I'd be very interested if you could switch to tg3 on the other box too, and see if you can reproduce the problem. It all depends on the traffic, phase of the moon, etc.. I'm afraid that isn't easy to accomplish. I am working with another researcher in a faraway land, and so I do not have direct control over their machine. Changing their nic could take a while. Sorry, ethtool can't be used to disable/enable NAPI. Ignore this idiot, neuron misfire... So,,, what's the conclusion?
