pentium bug continued [slightly offtopic]

I have something very strange to report.

I successfully crashed my box under linux with f00fc7c8.
I successfully crashed my box under win95 with f00fc7c8.
Both hard-froze, no mouse movement, no keyboard LEDs... etc.

The machine did not hard-freeze under DOS!!!! Though the debug program
locked, I was able to (a) toggle the keyboard LEDs with my keyboard and
(b) reboot the machine by pressing ctrl-alt-del.

This is very strange when compared to the opinions that have been
surfacing on this list lately.

I used the same method for crashing both DOS and windows. I started debug,
assembled the byte sequence and pressed "g".

contents of /proc/cpuinfo:
processor : 0
cpu : 586
model : Pentium 75+
clock_speed : 120 MHz
vendor_id : GenuineIntel
stepping : 11
fdiv_bug : no

This is an Olivetti P120S notebook with a mobile pentium in a socket.
