Boot from eMMC on i.MX6S: mmc0: Timeout waiting for hardware interrupt

Have placed u-boot in boot partition 1 and load up kernel and root filesystem via NFS, but receive error messages during bootup and every 5 seconds or so like this:


mmc0: Timeout waiting for hardware interrupt.

mmc0: Got data interrupt 0x00600000 even though no data operation was in progress.


The strange thing is that if I boot up with bootloader in SPI flash, still kernel and rootfs over NFS, the eMMC seems to be detected and working fine (I was writing out u-boot for instance..), so kernel and RFS is identical, also u-boot.


Any idea what can cause this..? this is on a custom board sharing much in common with Sabrelite, and kernel based on the 4.1.0 release.


eMMC is this one from Micron
