NetBSD pasillo.wsrcc.com 1.5R NetBSD 1.5R (WSRCC_INTEL) #0: Tue Feb  6 09:23:57 PST 2001     wolfgang@capsicum.wsrcc.com:/v/src/netbsd/src/sys/arch/i386/compile/WSRCC_INTEL i386

>Description:
	I can get reliably hang the above kernel when executing the 
	following ls/rm -rf/mkdir in rapid succession.

>How-To-Repeat:

	This happens on 2 different machines here where /home/wolfgang is
	Nfs mounted from another -current machine running a similar kernel.

	    alias dumptrash='echo dumping: ; ls -CFR ~/.trashcan ; /bin/rm -rf ~/.trashcan ; mkdir ~/.trashcan'
	    dumptrash

	    $ dumptrash
	    dumping:
	    <hangs here>

	I can't break into DDB at this point and must use the reset button.
	This happens both from an ssh to the remote nfs client and when 
	logging in from xdm.  I have just tried it 6 times and I get 6
	hangs.

	The dumptrash alias works as expected when run on the nfs server 
	(which has the files in a ufs).
