[Original Description] Happened while browsing the web with firefox. Suddenly everything (like the menu bar, launcher and window decoration) except for firefox tabs and the window with web page disappeared. When the PC's power button was pressed, a dialog with shutdown options appeared and it was possible to restart the computer normally.

The next time we attempt to wait upon the buffer (after userspace handles the signal), we believe that the buffer is idle and so skip the wait. There are a number of bugs across all generations which show signs of an overly haste reuse of active buffers.
