I'm using: Dell XPS M1330 laptop, Ubuntu 11.10 32bits, single boot (only Linux OS), Virtualbox (with Windows XP on virtual machine).

System crashed while working with a very heavy image on GIMP (and Virtualbox was on). During the same session, I made an automatic system update, but don't know what was exactly updated. After the crash the system doesn't boot. Always freezes on terminal screen but at different stages, ""Starting CUPS printing spooler/server", "Checking battery state", "mountall: plymouth command failed", etc. Sometimes indicates [failed] in some of the processes and sometimes they're all [ok].

Did a Boot info summary with boot-repair and gave me this report http://paste.ubuntu.com/1050743/

This is not a new install, have been using it for almost 6 months...though since last month it couldn't halt..it started shutting down and stopped at black screen with fan on and on/off light still on (I used to finish the shutdown process by forcing halt with a long-press of the power button). I don't know if these has anything to do with the boot failure.

Is there anyway I can solve this issue (the boot failure) or make some sort of system check to find out what is the cause of the problem?

I wasn't sure if this was the right place to ask the question, so I also did it at https://answers.launchpad.net/ubuntu/+question/201004
