>Description:
	
Since Jan 28 (last snapshot I had access to), and continuing till -current as
of March 09, 2001, the kue device hangs/pauses with transfers over a few 
kbytes in size.  This became evident when upgrading an IOpener from 1.5 
(which works perfectly) to -current.  Netbooting halts while trying to 
transfer 'init' over the network.  Booting from disk and mounting dirs over
NFS, doing an "ls" will work, but transferring a file of more than 1k will
cause the transfer to hang, and can only be aborted by a reboot (the system
does not return, even after 1 hour).

Using kue on a Sony Vaio (uhci rather than ohci) shows the exact same
behavior.  Using tlp rather than kue on the Vaio works fine with a March 09
kernel.

I'm not sure where to suspect, but 1.5 works fine, Jan 28 through current 
does not.
>How-To-Repeat:
	
Attempt to transfer more than 1-2k of data using a kue device.
