I have a wierd problem that when I switch runtime from 5 to 2 to do something, my network screws up when switching back to runtime 5. The harddrive lights in the front of my case never turn off and no networking features work at all. It doesn't do it all the time but a majority of the time when i drop to 2 and back to 5. I get no error messages, the network config says that my card is enabled and working.
Edit: I am using onboard ethernet on a Epox ep-8npa sli board. nForce 4 NB.
