I've run into a problem with Microport System V/AT 2.3 on an AT clone (no 80287). Floating point faults cause the system to crash. For some reason it only seems to happen after the second fault. Is this a bug in Microport's kernel and FP software? I've been trying to run the paranoia FP test program, it seems to be doing an excellent job of uncovering FP problems! -- John A.

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? Mark Zenier uunet!pilchuck!ssc!markz LOGGERMIST CROTEHAVEN
