I'm having the same problem - I'm running a server without any gui (no gnome app system monitor), no soundcard, but I have a 3c905 NIC.
I have found the following link describing the problem including a patch, but since it is on a production server, I don't have the posibility to verify it. https://bugzilla.novell.com/show_bug.cgi?id=227391 -- pci_set_power_state errors in tty0 console https://launchpad.net/bugs/66963 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
