 Dan,
 
 I think I have this!
 
 Can you try something:
 
 1. Apply the attached patch to $SRC/sys/compat/netbsd32/syscalls.master
 2. Re-generate the various syscall files using
 
     # cd $SRC/sys/compat/netbsd32
     # /bin/sh $SRC/sys/kern/makesyscalls.sh syscalls.conf syscalls.master
 
 3. Rebuild and install your kernel and modules
 
 I _think_ this will address all of the syscalls you referenced, except
 for osigvec which should already be handled correctly.
 
 Short analysis:  the syscalls.master file uses "sys" prefix for these
 syscalls, since they don't need a wrapper.  But it says to load the
 compat_netbsd32_43 module, while the actual sys_* implementations are
 located in the compat_43 module.  The patch tells it to load from the
 correct module.
 
 Thanks!
