Description of problem:

I've a MSI K8N Platinum with nforce4 SLI.
I've a problem with the integrated network and forcedeth: my network seems
works, but as you can see in the attchment some programs say that network
doesn't work, others yes:
- ping to www.google.it works
- browser can reach www.google.it
- network configuration says that eth0 is ok and working

but

- gnome's network icon say no network device
- network tool say that eth0 is inactive.
- Yum sometimes reaches repos sometimes not.


Version-Release number of selected component (if applicable):
kernel version: 2.6.11-1.1208-x86_64


Actual results:
network works not very well.

Expected results:
network fully recognized by any component.
