>Environment:
System: NetBSD 1.6 sparc64
Architecture: sparc64
Machine: sparc64
Platform: SunFire V100
>Description:

	attempting to use DHCP autoconfiguration during sysinst with the
	1.6 sparc64 INSTALL kernel on a SunFire V100 causes the kernel
	to drop into the debugger.

	Note also that it seems dhcpclient (or whatever's run right
	afterwards) wants to run 'date' near the end of its process, but
	it's not available.

>How-To-Repeat:

	Choose "DHCP autoconfiguration" in the sysinst process -- here's
	the trace as after that point as captured by conserver, with
	CR's and ESC's translated to ^M and ^[ respectively

	as you can see continuing to type "cont<CR>" eventually gets
	things running properly again.
