I am using Xkernel for my Sun 3/50 and occasionally Xsun crashes with
the error message "bad system call". This is repeatable and happens with
some programs like gtk-gnutella, or mpeg_play.

The version file claims
$Revision: 2.0.0.45 $ $State: Exp $
$Date: 1993/10/17 02:10:07 $
but some files are newer than that:

-rw-r--r--  1 rhialto  users  1585687 Aug 11  1997 Xkernel-root.tar.gz
-rwxr-xr-x  1 root     wheel  1827686 Mar 10  1997 Xsun*
-rwxr-xr-x  1 root     users   827549 Mar 13  1997 netbsd*

        NetBSD 1.2C (XKERNEL) #2: Thu Mar 13 23:40:24 CST 1997

Anything I can do, short of trying to cross-compile a new kernel (if
that even is possible in practice)?

-Olaf.
