We tried to use the new kernel, and it failed. It booted, but ipv6 was enabled, which appeared to make Jenkins only listen on the IPv6 addresses. Once I disabled IPv6, I realized eth3 (our internal Mellanox 10GbE card, ironically enough) was not visible to the system.
It then became apparent that something had activated some firewall rules that weren't activated before (port 8080 wasn't accessible on the internal network). Attempting to flush the iptables rules resulted in a complete locked. Bryon rebooted, I removed the upgraded kernel, and reverted to the default 10.04 kernel. The firewall rules that were blocking access to port 8080 went away when we reverted to the default 10.04 kernel. I wonder if something changed the default INPUT policy to DROP? I realized later that I did not try to modprobe the module for the Mellanox card, but that did not occur to me, since we had never had to do that manually before. We really cannot take this system down again. This is a system that costs us several hundred dollars per hour for downtime. Unless you have other ideas, we will have to find another way to trouble shoot this bug. ** Tags added: kernel-unable-to-test-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1158031 Title: Mellanox ethernet driver causing page allocation failures To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1158031/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
