Hi guys
As I was watching a movie I noticed my USB stick's light was flashing. Dmesg reported that the USB had disconnected. Curious, I removed and reinserted the USB stick. I was then greeted by this message:

Now, the reason for my posting this is that I can't reproduce the problem - it appears to have been a random fluke. So should I still report a bug?
Note: immediately below this message another one had started to appear on screen, but the system had locked up before that message had finished printing. Also, that second oops did not make it into the syslog. |

I wouldn't report it since it is not reproducible.

Make sure VirtualBox is the latest version.

hi,
I currently have same problem starting my winxp VM with virtualbox.
I think cause is some kernel modules because recently i've removed some modules from linux kernel and before all works correctly.

Oops: 0002 [#1] PREEMPT SMP |
this is the error and after that i can only poweroff my laptop with power button
