System: NetBSD balthasar.ipv6.stack.nl 3.0_BETA NetBSD 3.0_BETA (BALTHASAR) #1: Thu May 19 18:46:24 CEST 2005 martijnb@balthasar.ipv6.stack.nl:/usr/src/sys/arch/i386/compile/BALTHASAR i386
Architecture: i386
Machine: i386
>Description:
	The atu(4) device driver needs some work:

	1) Scanning for APs using 'wicontrol atu0 -D' yields "No APs found",
          even when they are available. In some cases, it will lock up the
          machine

	2) Kernel panic in ltsleep (in usbd_transfer; I can compile a kernel
          with less optimisations and jot down a complete stackframe if 
	  desired; the bug is reproducable) while trying to do IPv6 work.

>How-To-Repeat:
	
	1) 'wicontrol atu0 -D', and watch it fail.
	2) Cause some ipv6 traffic. It often fails on the first router
           solicitation (using 'rtsol atu0'), but sometimes it'll live for
           a few minutes. 
>Fix:
	Don't know :(
