System: NetBSD/evbarm on ADI BRH reference board
Architecture: arm
Machine: evbarm
>Description:
	gzboot is a standalone program used by NetBSD/evbarm which contains
	a gzip'd NetBSD kernel, much the way install kernels contain a
	ramdisk.  gzboot is then written to flash memory on the board, and
	when started, decompressed the NetBSD kernel from flash into RAM
	and jumps to it.

	The recent changes to sys/lib/libz have broken decompression
	of the kernel by the gzboot:

>How-To-Repeat:
	Attempt to use gzboot from March 29, 2003 sources.

>Fix:
	The problem goes away when the recent sys/lib/libz changes
	are backed out.
