I am having difficulty uncompressing the ramdisk. The ramdisk does uncompress
when I do not have FCC disabled in the kernel and it comes up to the prompt.
I cannot see how leaving at an option in .config would affect the ramdisk
from uncompressing.
I noticed that the code just hangs in huft_build in lib/inflate.c
(i.e. just a infinite loop).
Has someone else has seen this?
I added some debug info, which is illustrated in the output below.
