I've tried a few things. I did a blacklist ipv6, which seems to make it harder to trigger the condition with MythTV traffic (I was able to successfully watch a number of shows without the client locking up), but this didn't stop the case where any NFS transfers to my Slackware server locked up the client.
On a lark, I swapped the network card from the new e1000 to an old e100 card I had in a drawer. It locks up identically under NFS load: [ 341.152000] NETDEV WATCHDOG: eth0: transmit timed out [ 341.172000] e100: eth0: e100_watchdog: link up, 100Mbps, full-duplex [ 346.168000] NETDEV WATCHDOG: eth0: transmit timed out [ 346.188000] e100: eth0: e100_watchdog: link up, 100Mbps, full-duplex I suspect a deeper bug in the kernel, perhaps relating to interrupts, or the networking parts common to both code paths (where the skbs are transmitted). -- e1000 locks up under load in Feisty. https://bugs.launchpad.net/bugs/106869 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
