           Summary: Unplugging USB MP3 player from causes these printouts.
                    May be related to scsi subsytem.
    Kernel Version: 2.6.0-test3 and all the previous too
            Status: NEW
          Severity: normal
             Owner: greg@xxxxxxxxx
         Submitter: solt@xxxxxxxxxxxxxxxxx


Distribution: Debian SID
Hardware Environment: UHCI Intel Corp. 82801BA/BAM USB (Hub #2) (rev 12)
Software Environment: mount-2.11z, gcc-3.3.1, (on gcc-3.2.2 too)
Problem Description: After unplugging an USB MP3 player that uses scsi_mod, 
sd_mod and usb-storage, the kernel prints out these:

I reported this as early as 2.5.69.

Steps to reproduce:
compile the kernel with scsi_mod, sd_mod, usb-storage (all needed to transfer 
files to the usb device).

Plug in the device.
You can mount it, copy files, whatever.
Here's what you get about:
class_dev_release at drivers/base/class.c:201
and
kobject_cleanup at lib/kobject.c:402

Device class '1:0:0:0' does not have a release() function, it is broken and must 
be fixed.
