-current panic on netboot, NFS root?

["John D. Baker" <jdbaker%mylinuxisp.com@localhost>]

While trying to collect more data for port-sparc/46572, I tried a GENERIC
kernel from -current (about 201206140315Z).  (Need to boot with "-c" due
to port-sparc/34046.)  The results were as follows:


ok boot net-tpe -c
SPARCstation 10 (1 X 390Z55), No Keyboard
ROM Rev. 2.25, 128 MB memory installed, Serial #7410937.
Ethernet address c0:ff:ee:c0:ff:ee, Host ID: 72c0ffee.


Rebooting with command: net-tpe -c 
Boot device: /iommu/sbus/ledma@f,400010:tpe/le@f,c00000  File and args: -c
Lost Carrier  (transceiver cable problem?) 
Twisted pair cable problem or hub link-test disabled.
Use the PROM command "help ethernet" for more information.

ARP/RARP send failed.  Check Ethernet cable and transceiver.

This machine otherwise runs NetBSD-5.1_STABLE without any problems (once
port-sparc/34046 is worked around).

Anyone else tried -current on an SS10 lately?

Thanks.
