It's the first bug on the Microport bug list.  The C compiler produces
crap with floating point array or pointer expressions, and the floating
point emulator tries to use this.  Since the emulator is in the kernel,
the whole system dies.

I have the same problem.  Will getting a 80287 stop the system crash?
