The ThinkPad T500 has a SATA cdrom drive attached to an Intel ICH9M/M-E SATA ACHI controller. Upon inserting a disk into this drive, if sr-mod is loaded, the disk will never stop spinning by itself: it will spin up to full speed, then start slowing down, but just before it stops, it will spin up to full speed, then start slowing down, ad infinitum. If sr-mod is not loaded, the disk stops spinning right after insertion. It is only possible to remove sr-mod when the disk is spinning at full speed (all other times the module is in use), and then the disk stops. Mounting the disk also causes it to stop spinning (and it remains stopped after unmounting it). I see this behaviour with both 2.6.32 and 2.6.34-rc7.
Is something like hal, devicekit, etc. accessing the drive in this case? Can you try a minimal boot with no unnecessary processes and see if the same thing happens?
