NetBSD 1.5R NetBSD 1.5R (config.paalhuis) #0: Tue Feb 13 15:03:48 CET 2001 i386

When listing a big directory mounted over NFS, say the kernel build direcotory
or when using tcsh with tab to get a list, the kernel allways locks up on `netio'

``ps auxl'' giving :
root   292  0.0  0.1   292    4 p0- D     9:06PM 0:00.03 ls -al      0 292    1   0   2   0   292    4 netio    D    p0- 0:00.03 ls -al 

No network trafic is shown with tcpdump anymore. The fileserver is a NetBSD/sparc-1.5 and it doesnt matter if
the nfs mount is mounted with or without -s ... 

mount -t nfs machine:/usr/src /usr/src
ls -al /usr/src/sys/arch/arm32/compile/config.rangerover

it hangs :(
