I recently learned of a bug in the 80386DX processor version SX211.
The latest release of ISC UNIX 2.2 enables instruction pipelining,
causing my system to hang during installation of this new release.
I tried putting my drive and controller in another 386 box with a
different CPU, the OS installed fine.  I put the drive and controller
back in my system and tried booting the system.  The kernel panics
and dumps everytime it loads.  Can anyone confirm the pipeline bug
in the 80386DX processor version SX211 and explain just what instruction
pipelining is ?  I was told the SX219 version doesn't have this problem.
Is this the most current incarnation or the 80386DX ?  BTW, my processor
reads as follows:

	Intel
        80386DX-33   IV
        SX211
