[Bug 712175] Re: OMAP Beagle C4: kernel does not reliably find SD card on boot
Adding rootdelay=10 was one of the first things I tried and it made no difference. I haven't tried rootwait but that is documented as doing rootdelay=forever, so I would expect the same results. With my board, the problem seems to go away once it has been in use for a while. So it must be some kind of race or timing condition.

I still need to retest with a recent image, but rootwait/rootdelay isn't going to help here. This is a stock linaro setup with an initramfs, the kernel's built-in rootfs handling isn't used - and at any rate, the device *never* showed up until I removed the card and reinserted.

I intermittently get the same problem on a Beagle-xM running the latest code from inux-linaro-2.6.38.git I have the .config from the Alpha3 hardware pack but with Thumb2 enabled. In this, config. CONFIG_I2C_OMAP and CONFIG_GPIO_TWL4030 are 'y'. For a successful boot, no modules are loaded before the rootfs is mounted on the MMC.
