Hi folks,
I just upgraded my machine (N150 plus) to the latest kernel 3.2.0-30 for Lubuntu.
I had to find out that this somehow messes with the wireless and fan controls and thus also affects samsung-tools. Wireless on my N150P does not work with that new kernel.
I don't know what they changed exactly and did not have the time to read through the changelog thoroughly. I did some ad-hoc troubleshooting but could not get it to work in a couple of minutes so I am using the -29 kernel instead where everything works fine.
I'm going to submit a bug report on launchpad as soon as I find the time to (maybe tonight). I recommend not upgrading for the time being.
