eth0 timeout when system not being used for a while

[laurelraven]

I'm having an issue that I can't seem to find any help with online so far (maybe my google-fu needs some work).

I have a system that I built Gentoo on about a year ago, and it had been working fine for the most part, until the last three months or so. Now, when the system is left sitting for a few hours or overnight, sometimes when I get on it, it will not be able to get internet connectivity. Rebooting or restarting /eth/init.d/net.eth0 both fix the problem in the short term, but it happens again. Since it is my girlfriend's computer, and she doesn't want to mess with learning shell commands, I keep getting called in to "fix it".

So, I'm looking for a more permenant solution.

I pulled the logs from the system for today, since it happened again, and tracked down what looks like the error message when it first stops working:

Then it does the following error about once an hour after that:

Jan 11 10:35:53 [kernel] NETDEV WATCHDOG: eth0: transmit timed out

When I run '/etc/init.d/net.eth0 restart', it comes up fine and I get the following in the logs:

After that, I'm working fine.

I am running the '2.6.25-gentoo-r7' kernel, not a genkernel, for amd64.

I hope someone else out there either has seen this and knows what's going on, or at least is willing to help me solve this. Let me know if there is something I'm forgetting to post that might be helpful (the rest of the log, as far as I could see, was just a bunch of cron jobs running, and none running right before this happened). I appriciate any help.

Hi, it looks like kernel bug to me, you can announce it...

If you read the message, it writes:

[laurelraven]

Okay, I'm not at all sure I'm doing this right, and unfortunately won't know if it worked probably for a while (sometimes it doesn't have this issue for a week or more), but here goes:

I had noticed the "irqpoll" note in the error logs, but thought that it would have only made a difference if it were happening during boot up...I'll give it a try, though. Did not know how to add that as a boot option, but some substantial google searching has lead me to one person saying that you just add it to the end of the kernel line in GRUB.

I've added that, and am going to reboot. I'll post here if it doesn't work, and if it stays going fine for a while, I'll post that too.

Thanks!
