Problem Description: I compiled 2.6.21 kernel after doing make oldconfig to import running kernel configuration (2.6.20.3 kernel), but when booting with new kernel the system isn't unable to see any network interface.
In 2.6.20.3 kernel, my network interface works by forcedeth and sky2 modules, both changed in 2.6.21 kernel; so I think the problem is there.

Steps to reproduce:

Comment 1 Pol Hallen 2007-06-22 02:13:22 UTC

Hi,

i've a motherb. with the same chipset. I compiled last kernel 2.6.21.5 - after system startup my network is ok. But if i stress the network (ftp transfer for a long time) my network spin down.

At this point, i tried:

ifconfig eth0 down && ifconfig eth0 ip but my network don't ping

if I try to remove network module my system take me a long time.. and nothing appens.

I can only reboot my system.

Comment 2 Pol Hallen 2007-06-22 02:17:42 UTC

Have u tried with another network card?

I tried 3 several network card but I've the same problem.

Comment 4 Jørgen Elgaard Larsen 2008-07-22 18:21:59 UTC

Any news on this issue?

I recently upgraded from 2.6.18 to 2.5.26 and the NIC on the MCP61-based motherboard stopped working. Offboard NICs in the same machine (other chips, other drivers) works fine.

After the upgrade, dmesg says:
 forcedeth 0000:00:07.0: ifname eth0, PHY OUI 0x732 @ 1, addr 00:1d:7d:aa:1e:dc
 forcedeth 0000:00:07.0: highdma pwrctl mgmt timirq lnktim msi desc-v3

Later on, eth0 is assigned to the off-board NIC:
