The proper fix on FreeBSD is at Ah, good idea. The OpenBSD kernel doesn't log interface events, but this can be done nicely with ifstated (or people using OSPF can find the state changes in their ospfd logs). http://people.freebsd.org/~yongari/vr/ Diffing this against the old driver makes a lot of output with style changes as well as code changes so it's a lot to sift through, I've been working through it gradually but it's taking me a while... ___ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech

Glad I'm not the only one :-) For me, it does not happen as long as the interface is in promiscuous mode (ie. while watching to see if I can reproduce the problem). When I start tcpdump while the interface is in the hung state, I see the msg 'vr0: using force reset command.' and traffic resumes. -- aew ___ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech

What seems to fix it is a packet going on the outbound interface will 'unwedge' it so that the box can received packets once again. In the logs, a vr0: Using force reset command. will appear. It also seems to happen more frequently on vr0 than the other nics. Not sure if its an interrupt issue ? The newer version of the driver soon to go into HEAD seems to reduce the amount of force reset command that I see. I havent yet seen a situation where the interface stops receiving packets with the new driver. But then again, I cant make this situation appear on demand so I dont know if the problem is gone, or just less visible. ---Mike ___ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech ___ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech
