[CentOS] Loss of network connectivity | kernel: irq 68: nobody cared (try booting with the "irqpoll" option)

[P J]

James & Paul,

Thank you for your suggestions, I will give them a try.

Paul, it is indeed a SuperMicro with onboard Intel 82574L's.
So I will try the kmod-e1000e package as well.

Very grateful for your help to and to this list.

Thanks,
PJF
