           Summary: verbose mmc-related kernel messages slow down boot
                    process (GTA01)
           Product: OpenMoko
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: kernel
        AssignedTo: openmoko-kernel at lists.openmoko.org
        ReportedBy: thebohemian at gmx.net
                CC: buglog at lists.openmoko.org

The current kernel prints a lot of messages when accessing the MMC/SD-card (e.g.
when booting from it) which slows down the boot process considerably. The kernel
messages look like this one:

mmc0: req done (CMD18): 0: 00000900 d35983c7 befb4fff 92404021
mmc0:     1024 bytes transferred: 0
mmc0:     (CMD12): 0: 00000b00 7f5983c7 befb4fff 92404021

It would be nice if their urgency level could be lowered so that they only show
up when needed.
