Network error with Intel E1000 Adapter on update 2.4.25 ==> 2.6.3

Network error with Intel E1000 Adapter on update 2.4.25 ==> 2.6.3

[Martin Bene]

When trying to update the kernel from 2.4.25 to 2.6.3 I run into a probelm:

While the driver for the onboard Intel E1000 network adapter loads OK, it doesn't seem to find an interrupt for the interface - ifconfig shows:

eth0      Link encap:Ethernet  HWaddr 00:0E:A6:2D:7A:64
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000

          Base address:0x9000 Memory:fc000000-fc020000

Trying to configure the infterface results in a frozen system.

Running the system with 2.4.25 kernel works OK and shows 

eth0      Link encap:Ethernet  HWaddr 00:0E:A6:2D:7A:64
          BROADCAST MULTICAST  MTU:1500  Metric:1

          Interrupt:18 Base address:0x9000 Memory:fc000000-fc020000

and works OK.

Board is an Asus PC-DL, Intel 875P Chipset, one Xeon 2.8Ghz CPU, Onboard e1000 Network interface. Any idea how I can get the onboard NIC to work?

Thanks, Martin

full output of /var/log/dmesg || dmesg after bootup might help.

e1000 is known to have problems in 2.6.3

Please try the latest 2.6.3-bk snapshot, it may work better, it has
helped at least one other reporter of e1000 problems in 2.6.3

Some more information: 

* Update to 2.6.4-rc1 doesn't help, same situation as before.
* 2.4.25 finds/uses int 18
* Binary search shows that the problem first appears with 2.6.2-bk1; 2.6.2 works OK.

Further search shows that it's the e1000 driver update from 5.2.20 to 5.2.30.1 that breaks things for me. copying the older driver into a newer kernel works.

Hmm, changelog states what looks like a possible candidate: 

*   o Use pdev->irq rather than netdev->irq in preparation for MSI support.

Final information:

Backing out the pdev->irq <-> netdev->irq changes gives me ifconfig output with the correct interrupt listed; unfortunately, 
	ifconfig eth0 up 
still locks the machine, so that doesn't seem to be the only problem.

Martin, give 2.6.4-rc1 a try.  It removes a patch to e1000 that broke a
lot of folks with 875/CSA.

Thanks for the hint. Results:

 - Network interface works, no more lockups.
 - ifconfig still doesn't show the interupt being used.
 - /proc/interrupts DOES show the right interrupt.

experimenting with the driver source shows that the interrupt displayed by ifconfig seems to depend on netdev->irq being set; this was removed during the netdev->irq ==> adapter->pdev->irq change. adding the following line corrects ifconfig display:

Caching pdev->irq in netdev->irq is problematic because pdev->irq can
change after registering for MSI interrupts, for example.  netdev->irq
is vestigial from the days of manual irq assignment.

Bottom line is you'll not see the irq with ifconfig, but it'll be there
in /proc and lspci.
