DisplayLink software resets with quad monitors

[oldtopos]

Running quad 1600x1200 monitors (plus laptop display) causes frequent software resets of displays. The resets can be triggered in some cases by simply dragging a window over all display surfaces.

System has been rebooted; usb cable to laptop unplugged and replugged several times.

Triple monitor configuration is stable, and has run without issues for several days.

Initial and post event traces are attached.
