[Bug 11589] New: Mass-storage USB Device does not show up when CONFIG_SCSI_MULTI_LUN is set

http://bugzilla.kernel.org/show_bug.cgi?id=11589

           Summary: Mass-storage USB Device does not show up when
                    CONFIG_SCSI_MULTI_LUN is set
           Product: SCSI Drivers
           Version: 2.5
     KernelVersion: 2.6.26.5
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Other
        AssignedTo: scsi_drivers-other@kernel-bugs.osdl.org
        ReportedBy: nico@lifeisabug.com


Latest working kernel version: I *guess* all before 2.6.26
Earliest failing kernel version: Not sure. See above
Distribution: Gentoo Linux
Hardware Environment: Mobo: Abit IC7-G
Software Environment:
Problem Description:

The problem is about my mobile phone (Sony Ericsson K810i) which normally shows
up as two devices (phones internal memory and the memory card in it) when
plugging it to USB. Just like any USB Memory stick.

The phones internal memory is fine, it shows up as /dev/sdc1 with multi_lun
enabled or disabled and it does not show any warnings, thats how the memory
card in the phone used to work too. I don't know with what kernel version this
started, but let me explain it:

When CONFIG_SCSI_MULTI_LUN is set, the memory card does not show up as it
should, I only see /dev/sdd but not /dev/sdd1 - it's unable to mount it that
way.
When CONFIG_SCSI_MULTI_LUN is not set, it does show up as /dev/sdd1 but gives
me loads of warnings like "attempt to access beyond end of device", see dmesg
for that. This way it is mountable and works fine except the warnings.

Steps to reproduce: Plug Sony Ericsson K810i to USB and set it to file transfer
mode.

Another of those might-be-usb, might-be-scsi bugs.  Apparently a
regression, too.

If /dev/sdd shows up but not /dev/sdd1, then this is probably actually the
partition parsing code.  There was a change to reject badly formed
partitions; I believe someone is trying to revert that change.
