[E1000-devel] update on DG965RY kernel oops issue

[Andrew J. B. <and...@gm...>]

I am still having issues with my inbuilt e1000 hardware on my DG965RY desktop 
board after resuming from suspend-to-disk, but the error is no longer fatal 
to my network connectivity. Specifically, this is what happens: 

Trying to free already-free IRQ 21

 =======================
ADDRCONF(NETDEV_UP): eth0: link is not ready
e1000: eth0: e1000_watchdog: NIC Link is Up 100 Mbps Full Duplex
e1000: eth0: e1000_watchdog: 10/100 speed: disabling TSO
ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
eth0: no IPv6 routers present

As you can see, the link comes right back up. I have been working away for a 
while now and nothing has happened since this. This is kernel 2.6.19-rc3 with 
suspend2 for hibernation support. The e1000 driver is the version included in 
the kernel.org tarball for this version. 

I have MSI support enabled, I tried to disable MSI at boot time with pci=nomsi 
and this caused instability in my X server.

For what it's worth, I also had some issues with the Intel HD Audio hardware 
as well, but those were largely solved by disabling MSI on that particular 
driver. As far as I can tell this driver does not have such an option.

Please CC me any replies. Thanks.
