>Description:

Trying to netboot a -current kernel (as of last week) on a
SPARCclassic consistently fails with a "Watchdog Reset" during the
device probe sequence, always immediately after the message "scsibus0:
waiting 2 seconds for devices to settle..." is printed, like this:

   ok boot
   Resetting ... 

   SPARCclassic, No Keyboard
   ROM Rev. 2.12, 96 MB memory installed, Serial #187155.
   Ethernet address 8:0:20:5:56:13, Host ID: 8002db13.


   Rebooting with command:                                               
   Boot device: /iommu/sbus/ledma@4,8400010:tpe/le@4,8c00000   File and args: 
   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.

   ok 

The same kernel reliably boots on a SPARCstation IPX.

This is not a new problem; I had the same issue with a 1.6 kenel.
