[comp.unix.xenix] write, illegal instruction, XENIX 2.2.0

romwa@utgpu.UUCP (08/12/87)

I just finished installing 2.2.0 on a Sperry IT which was
formerly running 2.0.6.  Extra drivers in the system are for
Computone's serial i/o boards and for a Consensys 60Mb Archive
Tape.  We also have another Sperry without the extra drivers
in it and there is no evidence of this problem.

The problem is with the 'write' command.  The program returns
an error message 'illegal instruction' and then dumps core.
Occasionally the error message is 'Memory fault'.  I suspect
some collision with the drivers as this is not a problem on
the other system.  

Any help is much appreciated.
