Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage. I have classified this bug as a bug in lshw.

When reporting bugs in the future please use apport, either via the appropriate application's "Help -> Report a Problem" menu or using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

Please execute the following command, as it will automatically gather debugging information, in a terminal:

apport-collect 620114

This will help us to find and resolve the problem. Bear in mind that you may need to install the python-launchpadlib package from the universe repository. Additionally, when prompted to give apport-collect permissions for Launchpad you will need to give it at least the ability to "Change Non-Private" data as it will be adding information to your bug report. Thanks in advance!

Thanks NT Man.

Does the problem happen even if you enter the command lshw without sudo?

[Mikhail Gavrilov (mikegav)]

Without sudo system is functioning properly.

[Leo Arias (elopio)]

hum, so the problem is on sudo, on lshw or on the use of both together?

what about: "sudo echo" hello ?

[Mikhail Gavrilov (mikegav)]

Problem is on use lshw with sudo together.

I'll try to script something that starts it than immediately fires off an apport. I got maybe 8 seconds before the system froze, so I'll see if I can get it to run, get apport to scan it, then kill the process in that time.

I can confirm this bug. 'sudo lshw' hangs the system but only if I run the command two times.
When I run it first time I get:

'killed offer devices '

When I run it second time, it hangs.
