Kubuntu 14.04 LTS locks up shortly after starting virtualbox VM

Bug Description

Machine was running 12.04 LTS and worked fine, did not have any prior VirtualBox crashes.

After upgrading to 14.04 LTS, the machine consistently locks up about 10-20 minutes after starting Virtualbox and running a Windows 8.1 VM.

The symptons are system load goes really high, machine becomes unresponsive in GUI. I can change to a plain text shell, but then even a reboot command will not work. Have to hard reset the machine.

It is possible the issue is triggered by virtualbox when using a btrfs backend. After the system hung up, I looked at the syslog and saw these messages:

The problem is definitively the combination of Virtualbox and btrfs. I backed up my data, reformatted the file system where the virtualbox vms live using ext4 and the system has not crashed for 24+ hours now, whereas with btrfs it would crash within 20 minutes.
