I tried to reproduce the above error with the latest mainline kernel (3.15.0-11777-gb7c8c19). I am unable to reproduce this. I tried 5 back-to-back soft and hard reboots. Also, i observe that you get this error only with exynos_defconfig and not with multi_v7_defconfig. FWIW, I use a Transcend 8GB class4 micro SD card.
Yeah, I'm still seeing these errors after I fixed the power cable, and yes they only appear on exynos_defconfig, and not multi_v7_defconfig. Also, while these errors seem to come from MMC, I'm not actually using a rootfs on MMC, I'm using an initramfs.
