How old is your kernel? If your kernel's ixgbe.c is older than 1.88.2.13 please update the latest netbsd-8 and try. 1.88.2.13 (and 1.88.2.10) fixed serious interrupt problem.
I changed from 1.88.2.10 to 1.88.2.13. The problem was not solved. I have also tested the onboeard network card. After a few hours, the problem also occurred here. I still think it's a nfs problem.
It seems like the whole system is blocked. Not just the network. If no nfs drives are mounted, the problems will not occur.
Any ideas how to narrow down the cause? Many thanks for you efforts Regards Uwe
