Bug Description
System: Ubuntu 11.10
At arbitrary times, my laptop's CPU will max out and the system will come to a halt and it becomes almost unresponsive. Simple actions like opening a tty and logging in take 3 minutes+. I've yet to identify a culprit. A screenshot from htop during this unresponsive time is attached and can also be found here: http://
I would say about 75% of the time when this happens, I have a virtual machine running in Virtual Box and the machine is minimized. It also happens when the machine is in use, but not as often. The other 25% of the time it will happen without having a virtual machine running, so I've ruled that out as the cause. Most of the time Google Chrome is also running, but I've had this occur without Google Chrome running, as well.
I always notice, however, that the process "/usr/lib/
Whatever causes the hang up causes all the processes to hang. Most of the time I have to manually power cycle my laptop to resolve the issue (on restart, most of the time I have to let the laptop cool because the CPU won't let the system boot because it's over-heated). Sometimes I can kill Virtual Box or Chrome or another process taking up much of the CPU and the system will recover.
I've had this issue occur after long periods of uptime and also within 5 minutes of restarting my computer.
This has been an issue ever since I upgraded to 11.10. I'm currently using the classic gnome session, but I've had this happen in the other UI's as well.
