Comment:
Ralph,
Thanks for your suggestions. I straced the two hald-addon-storage and it appears one of them is polling my ide dvd drive and the other the scsi cdburner (logical!). Here is the output from the second one before and after I insert a cdrw (and the dmesg kernel error messages start). Note that if I do a cdrecord these kernel messages end I think because cdrecord is given a lock on the device.

There seems to be quite a difference there.
