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

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. ^ permalink raw reply [flat|nested] 4+ messages in thread

Making it support netpoll would be nice too. -Andi ^ permalink raw reply [flat|nested] 4+ messages in thread
