<!-- Converted from text/plain format -->
<P><FONT SIZE=2>I am having difficulty uncompressing the ramdisk. The ramdisk does uncompress<BR>
when I do not have FCC disabled in the kernel and it comes up to the prompt.<BR>
I cannot see how leaving at an option in .config would affect the ramdisk<BR>
from uncompressing.<BR>
<BR>
I noticed that the code just hangs in huft_build in lib/inflate.c<BR>
(i.e. just a infinite loop).<BR>
<BR>
Has someone else has seen this?<BR>
<BR>
I added some debug info, which is illustrated in the output below.<BR>
