There appears to be a problem with Support Level Supplement (SLS) xnx128.
It is supposed to correct the problems associated with internal modems
under SCO XENIX 286 2.2.3 and SCO XENIX 386 2.3.1, instead it corrupts
libio.a and causes the following error upon the next reboot...

TRAP 0000000E in SYSTEM, error code=00010002
   eax=FFFF0000,  ebx=00014E1C,  ecx=0200001A,  edx=000000A1

kernel: PANIC: non-recoverable kernel page fault

I am running SCO XENIX 386 2.3.1 with an AST Fourt-Port card.  I was
hoping this supplement would allow me to install some internal modems.
Fortunately the update backed up the original /usr/sys/io/libio.a, so I
was able to restore it to its original condition and compile/link a new
kernel.  Has anybody else on the net experienced this problem?

Do you folks at SCO (Ross?) have a fix for this?
