 Posted: Tue Jul 08, 2003 7:22 am Post subject: Seemingly random network lockup |
 |
|
The setup is this: At home I have an OpenBSD box connected to the Internet by means of ADSL. It does firewalling and nat and nothing else. My gentoo box is sitting behind the BSD box and the problem is this:
Every now and then when using Internet, the gentoo box locks up (no NumLock). I discovered that if I unplug the cable between the gentoo box and the hub and put it back in, the system resumes operation. I can also have the gentoo box unhang by pinging it from the BSD box.
The solution may be obvious but I fail to see it. I've searched the forums, but I may have missed the relevant posts. Before I start throwing hardware out the window I'm wondering if anybody as ever run across anything similar and could offer some helpful advice. The network card in the gentoo box (latest Gentoo-sources) is an onboard nforce. The hub I use is an old 10Mbit thing I picked up a couple of years ago. All network cards are 10/100Mbit. I realise that this information is not complete -- I'm writing this from work and I'll be happy to fill in the necessary details later. Thanks in advance! |

Does dmesg say anything about it? |

No, and neither does the log. |

If instead of unplugging it from the hub, you ifconfig eth0 down; ifconfig eth0 up; does that fix it? |

No can do. Since the machine is completely locked up until I unplug the network cable or ping it from the gateway, I cannot type any commands. But I can try if bringing eth0 down and up again will prevent any further lockups. |

It's very bizzare. What make/model network card is it? |

I've had somewhat similar problems with networking. My network would randomly lock up, and then resume after 30 seconds or so.
https://forums.gentoo.org/viewtopic.php?t=59009&highlight=
It did this with my wireless card and wired. I never figured it out...I just started over from scratch (it was my first Gentoo install). 
I wouldn't start tossing hardware.

Actually that's just what I did.
I bought a new realtek card (they're not so expensive), recompiled the kernel with the appropriate module, removed nvnet from modules.autoload and now networking works without lockups. Whether there's something funny going on in the NVIDIA module or not I don't know. If there'll be an update I'll try it again.
Thanks for your replies! |

| Some time has passed, and there surely has been an update or two to the nforce-net drivers, gentoo-sources and probably a bunch of other stuff that could have been the cause of this problem. Anyway, now everything works the way I expect it to. |
