You can try to edit /etc/dbus-1/event.d/20hal and change the line
set -e
to
set -xe
Then you can restart dbus and all commands in that script will be echoed
to STDOUT as they are run. Maybe that will give you a clue where things
go wrong.
(A quick look in /usr/share/doc/hal did not tell me anything. NEWS.gz
states that a kernel >= 2.6.17 is needed but I did not notice any
specific modules being mentioned.)
