We're using Zen 6.5 and workstation imaging has been working fine for a
while, now whenever we try to take an image of a workstation it freezes at
the line "Load USB modules".

This happens if we tell the workstation to take an image on the next boot
using the eDir object or if we press Ctrl-Alt on boot to start the PXE.

The stranger thing is if we press random keys (Shift and any letter keys)
repeatedly while at the screen where periods are flowing down the lines
and it says "Uncompressing and loading ZenWorks imaging" it seems to
overflow the buffer and it doesn't freeze at this point.

Any ideas?

Thanks for the help.
