That was nice for you to point out. I am working on this computer for hours now and I have some more information to help you.

About the ping, as we can see in the interrupts the nvidia card and the NIC are sharing IRQ11. That answers why the video driver exits when we ping the NIC card. It fires an IRQ11 and the nvidia driver does something strange and all becomes working again.

Also, I didn't mention that the error I'm getting is

NVRM: Xid: 8, Channel 00000001
NVRM: Xid: 16, Head 00000000 Count 00000004

Or variations like that. So now this problem becomes more clear, but still no solution to it.

What could be the Nvidia driver be doing because of this IRQ11 sent by the NIC? Maybe this IRQ is causing it to abort something it was doing and letting the system stable.

Thanks for your attention and I hope we find a solution for all of us.

Best wishes,
Rodrigo Madera
