- The same issue is seen when I configured IP via dhcp or statically assigned IP over pci-pt shiner T adapter interface either.

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode.

To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/1497966/+editstatus and add the package name in the text box next to the word Package.

[Tim Gardner (timg-tpi)]

Is this still an issue ? It seems pretty important for nobody to have complained since the bug was filed.

[Mauricio Faria de Oliveira (mfo)]

Tim,

This looks like the same deal w/ the other bug today; closed as unreproducible, which was not reflected here.
I'll pass this on to the bug bridge team.
