Subject: forcedeth trouble in 2.6.34.6 ?

  Hi,

  I'm running a 2.6.34 (64bit) with Fedora 13 using the forcedeth
network driver. Sometimes a ǵo I noticed that the driver fails
to initialize the network connection properly. The HUB tells me
I have a connection and ifconfig and ethtools seem to report
the card as being properly set up. But nothing goes over the lines.
No DHCP or any other communication. Removing and inserting the
driver (sometimes more then once) solves the problem.

  Since the hardware is rather old I thought the NIC is broken
and I added another card. Now I have set up a new computer with
another nvidia chipset and have to find out that
it seems to be a driver issue.

  I found some random complains about the NIC and the driver in the
net which seem to report similar issues (NIC dead on boot etc..)
but all of these seem to refer to older kernels like 2.6.27 and
such. There also didn't come up much under bugzilla.kernel.org
for 2.6.24 when I search for forcedeth

  Is that a known issue ?

Cheers

  O.
