I maintain the ide-cd code and the uniform cdrom driver. This first step will make uniform be quite verbose. I am assuming you are using a 2.1.x kernel. With a nice shiny new kernel I have added some debugging stuff that may help narrow down where the problem lies. Add the following:
options cdrom debug=1
to your /etc/conf.modules file. This should produce copious kernel messages from uniform. I'd recommend doing this from a console -- not X -- in case the messages don't hit your hard disk. I can't guarantee I can fix this one, depending on where it lies, since I suspect the problem lurks inside the ufs code, not the cdrom driver, ide, or scsi layers. This should (hopefully) at least give us a look into _where_ the ufs code chokes.
