Hi Søren!

Can we please continue to discuss this on ubuntu-users? This way other
people can benefit from it, too. Thanks!

Oops, I did not see the status flag "Ds" at first look. This indicates
that hald has crashed and hangs in an I/O operation. This explains why
its not responding for removable devices and the Device Manager.

We already had such cases in the past, when hald just crashed with
a particular piece of hardware. I would really be interested in the
cause of it.

So before I propose to start the debugger, can you please open a
shell, and do the following:

  sudo killall hald # kill the hal daemon which has crashed anyway

  sudo hald --drop-privileges --daemon=no 2>&1 | tee /tmp/hal.log
  # start hald without detaching from the terminal

The second command writes hal's debugging output both to the terminal
and to /tmp/hal.log. Then please look at a second console if  hald has
already crashed (ps aux|grep hald), quit hald by pressing Control-C,
and mail me /tmp/hal.log.

I hope that I can find something from this log. If not, we have to do
some more intrusive things :-/

Thanks very much for your cooperation!

Martin
