Hi,

  I  insert SDHC 4G into SDIO slo9
  t in my Sheevaplug.
  It does output following message(dmesg) and I can not access SDIO.
  ----------------------------------------------------------------------------
  mvsdmmc mvsdmmc: timeout for cmd51
  mvsdmmc mvsdmmc: timeout:trying to call interrupt routine
  mvsdmmc mvsdmmc: interrupt not handled!!! int status = 0x810
  mmc0: error 110 whilst initialising SD card
  ----------------------------------------------------------------------------

   Kernel version is
   Linux version 2.6.22.18 (dhaval@devbox) (gcc version 4.2.1) #1 Thu Mar 19 14:46:22 IST 200
   (Nothing changed after I received Sheevaplug).
   One thing I am concerning is that while Sheevaplug is booting, kernel output followings.
   ------------------------------------------------------------------------------
   sdhci: Secure Digital Host Controller Interface driver
   sdhci: Copyright(c) Pierre Ossman
   mvsdmmc: irq =28 start f1090000
   mvsdmmc: no IRQ detect
   ------------------------------------------------------------------------------
   But I don't know how I fixed.

   Any suggestion are welcome.

   Thanks :

try do this and see if it can mount

root@ubuntu:~# fdisk -l
root@ubuntu:~# mount /dev/mmcblk0p1 /mnt/
root@ubuntu:/# touch /mnt/test1
root@ubuntu:/# cd /mnt/
root@ubuntu:/mnt# ls

test1 file should be created.

I have a similar problem to the original poster.

In dmesg I get:
sdhci: Secure Digital Host Controller Interface driver
sdhci: Copyright(c) Pierre Ossman
mvsdmmc: irq =28 start f1090000
mvsdmmc: no IRQ detect

and there is never any device with a name mmblk* created in /dev when I insert an SD card.

I am using the 2.6.22.18 kernel that shipped with the plug (I know this doesn't work for booting from the SD card, but I am just trying to follow the wiki instructions to create a root filesystem).

Is there something more I need to do, or is the plug broken, or what?

Thanks,

Jon
