           Summary: I get a kernel OOPS! If I try to attach an usb card
                    reader, SD, MMC, ecc.. to my Slamd64
           Product: IO/Storage
           Version: 2.5
     KernelVersion: 2.6.26.2
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: blocking
          Priority: P1
         Component: SCSI
        AssignedTo: linux-scsi@vger.kernel.org
        ReportedBy: pinc_o@yahoo.it


Latest working kernel version: 2.6.25.x
Earliest failing kernel version:
Distribution: SLAMD64 12.1
Hardware Environment: Asus A7 deluxe
Software Environment: KDE/command line
Problem Description:

If attach my usb card reader, without load mmc_block an mmc_core modules, then
the follow OOPS appear(If first load them, simply doesn't mount the SD. Please
note: I always use "automatic loading kernel modules" compiled in "my" kernelS.
But from many time, the recent kernelS not load the mmc_block module):
