>Description:
When I recently tried to use "xplore" - Linux-i386 2.0.x ELF binary because
I have got Motif for Linux but not for NetBSD - under NetBSD 1.3 my system
drops into DDB with this message:

kernel: page fault trap, code=0
_nfs_enterdircache+0x84:	movl	%edx,0(%ecx)

A "trace" give this output:

_nfs_enterdircache+0x84
_nfs_bioread+0xc41
_nfs_readdir+0x79
_linux_sys_getdents+0x2a

After trying a few things out I could repeat the bug by accessing the
map directory of my auto mount daemon with a Linux "ls" binary, too.
It doesn't happen if I use either a NetBSD binary or a normal NFS
mounted directory.

>How-To-Repeat:
Use a Linux "ls" binary on a map directory of "amd".

>Fix:
Sorry, I don't know.
