[Margin note: bcm43xx doesn't work on my test boxes although it used to on one
of them, but I have to play with it a bit more.]
It looks like i386 cannot shut down cleanly with this kernel. On my test
boxes (2 of them) it hangs after killing all processes, 100% of the time.
Fortunately the console remains functional so I have used SysRq to
collect some traces (below).
Greetings,
Rafael
