It looks like it is running to me - what was the problem again?

Is this the one where you had only a partial transfer by fastboot?
partial because fastboot silently fails is the image is too big.
I.E: you may have part of the new image and part of the old image on the device. not good(tm)

Let see if I can give you some hints, with:

Code:

Menu
====
3. Load MMC0 over USB storage
4. Erase MMC0
I. Initialize Partition Table (fdisk) and format FAT
O. Format and overwrite FAT partition
E. Export FAT partition
U. Update using update*.bin file on FAT partition
M. Update using update*.bin file on FAT partition of second MMC port
D. dmesg / kernel printk ring buffer.
Q. quit

Select E - connect USB cable to PC
transfer the amazon update file to top level of visible USB storage
remove cable
(the system will automatically un-export USB storage)
Select M
wait - it should reboot by itself when done.

NOTE:
Do not try to transfer the main rootfs.img file using fastboot - the Kindle fastboot can not handle a file that large (it is larger than available ram as it un-compressed).

You can transfer the kernels and the diags system image - fastboot can handle those file sizes.
(except maybe not on the KOA2 - diags no longer has a partition to itself)
