Subject: Re: [uml-devel] actually useful backtrace from a CPU-chewing hang
Date: Fri, 09 May 2008 19:13:22 +0200	[thread overview]
Message-ID: <1210353202.31648.8.camel@localhost> (raw)
In-Reply-To: <20080509151604.GC10169@c2.user-mode-linux.org>

For the "date --set" back 5 sec on the host that 
freezes an uml indefinitely 
(in kernel/time/timekeeping.c, update_wall_time,)
then download 

plug_and_play_clownix_network_03

at http://clownix.net

On my host, it does get stuck, but it may depend also on
host and host kernel, I have: 

uml_clownix_net$ uname -a
Linux localhost 2.6.22.15.tex1 #1 SMP Sat Dec 15 13:15:05 CST 2007 i686
Intel(R) Core(TM)2 Quad CPU    Q6600  @ 2.40GHz GNU/Linux


The download is long, the untar too, but the freeze is garanteed!

to start after download: 

"./start_clownix_net virtual_platform_configs/single_machine"

Hope you try it!
