Transmitter of CK804 hangs hard, needs power cycle to recover

Hi Manfred,

I filed BUG 6480 describing the problem and providing lots of info. If you need more info, just ask.

At the moment I have no idea about the reasons. Except Crossover-Cabling vs. using a switch.

The machine is a production machine, so I cannot test kernels and patches.

But I have several machines with identical hardware where I can test this.

Once we can reproduce it without a Sonicwall, I can build a test setup using any kernel hackery required to resolve the issue :-)

Could you please contact the right nVIDIA people, if needed?

PS: Stephen, you are not CC'ed from bugzilla and
"agreed to help out with net driver maintenance"
so I CC'ed you here manually.

Regards

Ingo Oeser

Has anyone looked into making this driver use NAPI? This would fix the IRQ overload problem and a number of other DoS risks. Also, if done right the device lock could be reduced to just a transmit lock.

Making it support netpoll would be nice too.
