[OE-core] wic debug suggestions

[Philip Balister]

I'm trying to make an sd card using the sdimage-bootpart.wks file. I've
made an image and dd'ed it to a card. The card has a good vfat
partition, but the ext4 partition won't mount. Looks like bad
superblock. I can format the partition manually, so partitions seem OK
and card works.

Does anyone have any suggestions for debugging this?
