I recently installed tuxonice on a Toshiba z830. I have ubuntu 12.04 (kernel was: 3.2.0-26) I wanted to be able to hibernate, which I consider to be a basic thing a OS should allow you to do. Well, it didn't work...but they already tell you it may not so I removed it. For doing all these I followed:

Problem with Hibernation

After uninstalling I switched off the laptop and after this I started to have several problems. The first one was that Cisco VPN didn't work anymore and then I realised that I could not even suspend my laptop. I found very strange that after removing tuxonice I still had this:

/lib/modules/3.2.0-26-generic-tuxonice/

The VPN problem could be solved by just copying from my previous kernel: 3.2.0-26-generic/CiscoVPN/ into the tuxonice one. Not very elegant but works.

Now, for the suspend problem (and the previous too) I can hold Shift when starting and select my old kernel and then suspend works again.

In my opinion tuxonice was not correctly uninstalled as it left that kernel behind and worse: ubuntu uses it if I do not take action. I have these work arounds....and here is my question:

how can I delete this tuxonice kernel safely? If you need more info please let me know.
