I continue to see this bizarre problem with my network interface on
an SS20 box.  For example, I will include below the dmesg output from
the current netbsd.GENERIC_SCSI3 kernel with the 1.4 release and that
for a GENERIC_SCSI3 I built on the system (that was built using the
kernel netbsd.GENERIC_SCSI3 from the Apr 23 1.4_BETA snapshot).  I
tried building my own GENERIC_SCSI3 kernel on the weekend and get the
same le0 failure... help!  Do I have bad hardware, or something flakey?
Everything seems to work like a charm with those kernels that don't
fail at boot.  But they either work or don't - no sometimes about it.
