Flashing eMCC hangs at "task mmcqd/0:70 blocked for more than 60 seconds"

I am trying to flash BBB-eMMC-flasher-debian-7.8-lxde-4gb-armhf-2015-03-01-4gb.img and bone-debian-7.8-machinekit-armhf-2015-03-15-4gb into my BBB, it went into LEDs cycling fine, but then hangs in the middle.

I hook it up to the serial console, and it says (both images and after retry many times):

you dont have a 4gb emmc on your BBB ?

I believe I do, that’s what I ordered for.

df says:

Yet dmesg says:

Is this something I should worry? or is that just an generic name of the firmwre?

It's just the generic name..

"INFO: task mmcqd/0:70 blocked for more than 60 seconds." is usually a
sign of "picky" mmc microSD media for our ancient 3.8 kernel..

Try using a different microSD card.

Regards,

I had a similar problem. Swapped cards and it worked fine. My old card (4GB) worked with 7.5*** but not with any image above that. Now i used a spare 8GB one and i was able to flash the BBB-eMMC-flasher-debian-8.0-console-armhf-2015-05-08-2gb.img to my BBB. Weird.
