Hi,
I'm experiencing  a really strange issue with kernel 3.7.1.

When I power up olinuxino, kernel runs without problems and root fs is mounted correctly. But if a "reboot" command is typed on command line, when the kernel restart it's unable to mount SD card partitions. The only way to start olinuxino is both power it down or press RESET button.

These are messages on kernel ring buffer when board is powered up:

I tried to add a rootdelay=3 to kernel cmdline, but it doesn't solve.

Help is really appreciated.

I discovered that the same problem affects latest ArchlinuxArm for olinuxino.

Same for 3.8.0-rc3.
mmc is initialized at reboot, but no mmc0 discovered.

Same here with 3.7.6 and latest Arch Linux image, really annoying because I cannot use the watchdog timer to let it reboot automatically on errors.

Edit: Reboot works if you use U-Boot: http://www.eewiki.net/display/linuxonarm/iMX233-OLinuXino, http://www.jann.cc/2013/02/07/u_boot_for_the_imx233_olinuxino.html.
