System: NetBSD wsrcc.com 1.3_BETA NetBSD 1.3_BETA (GENERIC) #40: Tue Dec  2 12:56:07 PST 1997     root@atomic.clock.org:/usr/src/sys/arch/sparc/compile/GENERIC sparc

>Description:
	xdm locks up the le0 driver with the following syslog:

    Dec  3 23:08:03 wsrcc /netbsd: le0: lost carrier on UTP port
    Dec  3 23:08:08 wsrcc /netbsd: le0: device timeout
    Dec  3 23:08:08 wsrcc /netbsd: le0: lost carrier on UTP port
    Dec  3 23:08:13 wsrcc /netbsd: le0: device timeout
    Dec  3 23:08:23 wsrcc /netbsd: le0: lost carrier on UTP port

This only happens if xdm is started.  If xdm isn't started, then le0
will work just fine (just like its always worked for me for approx 1
year under netbsd/sparc).

Note, this bug will *not* happen when X is stated via startx.  It only
happens under xdm.

The X11 used was compiled from sources sup-ed from "xsrc" on the
afternoon of 12/2/97.  The only changes to a stock install were to
uncomment the following line in xc/config/cf/site.def , and copy in
the "Wraphelp.c" file.

/* #define HasXdmAuth YES */
