This must have been one of the original 8086's.  I didn't read it
here originally (I can't find my original source), but in Stephen
P. Morse's _The_8086_8088_Primer_ (Hayden 1982, AKA "the red book"),
pp 89-90, subtitle \fB An 8086 Mistake \fP:
	[ describes the above problem ]
	This mistake was not discovered until after the 8086
	was designed and built.  After the mistake was dis-
	covered, the 8086 was modified so that it will not
	accept any interrupts immediately after executing an
	instruction that moves a new value into SS.
Says nothing about whether old chips were recalled, or what ...
