Sounds like ES:BX is a NULL pointer
(you forgot to list BX, though).
And as ES == NULL == evil, this results in a privileged instruction exception.
Try to find out where the NULL pointer comes from via relay trace
or by walking the function backtrace (checking where ES:BX gets loaded
and where this memory location or register gets its value from).
