Bugzilla Bug 90069

After upgrade from gentoo-sources-2.6.9-r14 to gentoo-sources-2.6.11-r6 the NIC
sometimes stop working and remains blocked also after reboot. No packets is
coming in or out through this NIC.

In the /var/log/messages the errors appears:

The only solution how to get out of this blocked state is to turn off computer
completely (plug out it from electricity). For me it happens 1 or 2 times in a
day. It depends on network traffic (lot of traffic - bigger chance to block the
NIC). This does not happen with 2.6.9-r14.

My mobo is MSI K8N Neo4 Platinum (nForce4 chipset). I'm using forcedeth module.

Please test vanilla-sources-2.6.12_rc3

Tested. Same problem with vanilla-sources-2.6.12_rc3. :-(

Please file this as a bug at http://bugzilla.kernel.org and post the bug URL
here.

Well, here it is:  http://bugzilla.kernel.org/show_bug.cgi?id=4552

Looks like its fixed in forcedeth 042. Will include in next gentoo-sources
release.

Same problem on my new MB ASUS A8N SLI Premium nFOrce4 chip set on CPU
AMD X2 3800+ 2G RAM and try to run Gentoo LiveCD 2005.1 and have problem running.

Best Regards

Fixed in gentoo-sources-2.6.13
