A few days ago I set up my laptop (Atheros 5212/5213) with LM KDE and it worked great. It came with kernel 24-19 and the updater brought it to 24-21. Currently there are some kernel headers, etc being held back. I installed the linux mint package of virtualbox-ose and all was well. It would not run as it didn't have all of the required packages (headers, etc). Pretty poor packaging, but oh well. I installed vitualbox-ose (something) generic as the virtualbox error message recommended. All seemed to go well, but after the install, the 24-21 kernel will no longer load the restricted drivers for the Atheros wifi, hence no network and it also seems to have broken the DVD drive as it is throwing off errors and won't mount. Booting to the 24-19 kernel my wifi and DVD work fine. Of course virtualbox doesn't work because the headers, etc are not installed. I am not going to try it as I don't want to be left with no network at all. Is this a known problem? It certainly wasn't a problem in Kubuntu Hardy, so I assume it is a packaging/repository problem. Is there any way to get around this? I don't have to run the latest kernel, but I do need virtualbox to run XPH.
