For comparison, here is the corresponding log I got when I unplugged a USB CD-RW device, minus several lengthy and uninformative stack dumps following the "Badness" lines -- did you enable debugging in lib/kobject.c? It looks like there are a number of messages present in mine and missing in yours. Tracking them down may provide you with some valuable clues. A good place to start looking is in drivers/scsi/scsi_sysfs.c. Oct 4 11:31:16 patience kernel: usb-storage: -- dissociate_dev Oct 4 11:31:16 patience kernel: CLASS: Unregistering class device.
