Interesting.

Entire possible and not unlikely given the logs. However, on shutdown
hald does terminate all helpers. I'd be very surprised to see this on a
fresh reboot unless the installation of hald is screwed.
This is what I get on my system
# ps ax|grep hald-addon-storage
1593 ? S 0:06 /usr/libexec/hald-addon-storage
14451 ? S 0:00 /usr/libexec/hald-addon-storage
14462 ? S 0:00 /usr/libexec/hald-addon-storage
14465 ? S 0:00 /usr/libexec/hald-addon-storage
14467 ? S 0:00 /usr/libexec/hald-addon-storage
with a 6in1 card reader (4 LUNs) and one optical drive. Maybe I should
make hald-addon-storage should tweak argv[0] to print what device file
it's polling. That would ease debugging quite a bit :-)
Christian, can you confirm you only have a one copy of
hald-addon-storage per LUN of of your card reader? (plus one for your
other removable or hotpluggable storage device)
