System: NetBSD babylon5.localhost.fi 1.5_BETA NetBSD 1.5_BETA (BABYLON5) #111: Sat Oct 21 16:36:48 EEST 2000 pooka@babylon5.localhost.fi:/sources/src-1-5/sys/arch/i386/compile/BABYLON5 i386


>Description:
	The server is NetBSD 1.5_ALPHA. The only thing unusual about it is
	that the exported filesystem is LFS. Every time I start to do a
	cvs co pkgsrc the client box just panics. It usually gets a few
	files before going berzerk, never more than 10.

	I could, however, checkout the src module completely succesfully and
	eg. build a kernel on the nfs mount.
