Hi,
Seem something is wrong with rawhide arm images.
It is a problem with mounting 4rd partition with rootfs.
After writing image to sd card using fedora-arm-image-installer 4th partition cannot be recognized as ext4 and looks like by boot fails on remounting to rootfs on sd card:
# file -s /dev/mmcblk0p{1..4}
/dev/mmcblk0p1: DOS/MBR boot sector, code offset 0x3c+2, OEM-ID "mkfs.fat", sectors/cluster 4, reserved sectors 4, root entries 512, sectors 59392 (volumes <=32 MB) , Media descriptor 0xf8, sectors/FAT 60, sectors/track 32, heads 64, reserved 0x1, serial number 0x9a574bdf, unlabeled, FAT (16 bit)
/dev/mmcblk0p2: Linux rev 1.0 ext4 filesystem data, UUID=478eb925-9ca1-444a-800e-2ced04ee699f, volume name "_/boot" (needs journal recovery) (extents) (64bit) (large files) (huge files)
/dev/mmcblk0p3: Linux/i386 swap file (new style), version 1 (4K pages), size 62463 pages, LABEL=_swap, UUID=634545e1-7b96-40b2-850c-8d5f6cf69be3
/dev/mmcblk0p4: data
Strange because I still can mount this partition from image file by:
