In my test environment, I have 2 servers, each of which has a sky2 Marvell NIC connected to a switch as "eth0". On server "B", I type "nc -l -p 3409 > /dev/null" On server "A", I type "nc server-B 3409 < /dev/zero" I see lots of traffic from A->B, as would be expected. If I shutdown eth0 on server "B" using "ifdown eth0", wait a few seconds, and then re- enable eth0 on server "B" using "ifup eth0", I see the following in "dmesg" output on server B: sky2 eth0: disabling interface sky2 eth0: enabling interface sky2 eth0: ram buffer 48K sky2 eth0: Link is up at 1000 Mbps, full duplex, flow control rx ip_tables: (C) 2000-2006 Netfilter Core Team As expected... The problem is that server B can occasionally end up in a state where it is unable to ping or access the local subnet anymore. Both "mii-tool" and "ethtool eth0" shows a link present. If I perform "ifdown eth0; ifup eth0" on server B, it doesn't help anything. If I unload the sky2 module, then things clear up and I'm back on the network again. I'm curious about this testcase because the symptom seems to match the earlier "tx timeout" messages; the driver tried to re-enable itself after a timeout, but it's still not able to see any traffic. Steps to reproduce: See "Problem Description" above. While traffic is continuously being transmitted from server "A" to server "B", shutdown the network interface on server "B", and then start the interface on server "B". Monitoring RX traffic on server "B" will indicate when it is no longer receiving the bytes sent from server "A".

No longer using Ubuntu on machines with this hardware.

[Bug 114019] Re: sky2 driver "tx timeout" with large uploads
It appears that with 2.6.20-16 the connection just hangs without anything being printed to syslog or dmesg, and rmmod/modprobe of the the sky2 module is required to get the device working again (I waited over half an hour after ppp/vpn connections stopped working). In 2.6.20-15 it would always printed the "tx timeout" messages within minutes after the connection failed, and automatically reset itself without human intervention. -- sky2 driver "tx timeout" with large uploads https://bugs.launchpad.net/bugs/114019 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
