Ayaz Abdulla wrote: For all those who are having issues, please try out the attached patch. Will try. I reverted to 2.6.19 w/o suspend/resume patch last weekend to make sure on 2.6.19 forcedeth is stable and noticed something odd: Because I didn't include the suspend/resume patch I obviously had to a down/rmmod/modprobe/up cycle after each resume and I noticed that the behaviour seems to alternate between resumes: Behaviour 1: After modprobe I get two interface 'eth0' and 'eth1' for the two ports, as expected. Behaviour 2: After modprobe I get one interface 'eth3' (which should be 'eth1') and one interface with increasing numbers (which should be 'eth0', last resume it was 'eth12' IIRC). As I said if I get behaviour 1 on one resume I get behaviour 2 on the next resume and vice versa. That seems rather odd to me. On a not quite related note, forcedeth shows a different ethtool output (compared to e100), when no cable is connected to the port: forcedeth, no cable connected: |Settings for eth1: | Supported ports: [ MII ] | Supported link modes: 10baseT/Half 10baseT/Full | 100baseT/Half 100baseT/Full | 1000baseT/Full | Supports auto-negotiation: Yes | Advertised link modes: 10baseT/Half 10baseT/Full | 100baseT/Half 100baseT/Full | 1000baseT/Full | Advertised auto-negotiation: Yes | Speed: Unknown!

There are many forcedeth changes in git-netdev-all.patch. Can you
try reverting drivers/net/forcedeth.c back to the unpatched version
from 2.6.20-rc6?
Thanks.
That's essentially what I did, it didn't appear to help. I assume
the
problem must lie elsewhere..
doh, I missed that.
It's presumably not the driver and nobody else seems to be hitting
this, so
it must be something peculiar to your setup. But I don't know what it
might be, sorry.
Actually it has been reported by several other people here including
myself but it seems to have been overlooked here ;)
See the messages with forcedeth in the subject line over the past few
weeks.
I put 2.6.20-gentoo on my machine this weekend with debug printks
enabled and right now I have yet to lose connectivity -- going on ~20
hours worth.
Previously I would lose connectivity within minutes of booting up. I
had a script set up that detected the ping loss of a gateway and would
restart both interfaces (dual onboard nics).
Tonight I will disable the debug printks and see if the system remains
online. There was a big patch applied to forcedeth for 2.6.20,
previously I was having these issues for several of the -19 series.
