Hi,

Am on the 64bit version of 12.04 on Dell xps L502x. Generally things work ok. I'm using bumbleebee, but other than that everything standard.

Problem I have is that sometimes the system hangs during boot. I've got a black screen full of text, the mouse cursor appears and then... nothing.

Interestingly the last line of text prior to the crash/hang varies. e.g. "Starting crash report submission daemon" or "Stopping save kernal messages". The only unifying factor is the hang, and the mouse cursor appearing.

Any advice on how I can go about diagnosing this would be much appreciated. To reiterate, the problem is intermittent, which is confusing the hell out of me.
