About the cramfs

[=?gb2312?q?=D0=C2=20=D4=C2?=]

hi!
         I was creating the cramfs image using
/linux/scripts/mkcramfs.c,because of the big endian,so
I got 
a patch to convert. 
        When I mounted the cramfs as root
filesystem,it worked, and to read directory was also
ok,but When 
I tried to read the files ,I found that it didn't work
well.Sometimes,error emerged as follow:
           bash>Error -3 while decompressing!
             00158fb8(67829187)->001f0000(1024) 
and I used system page size is 1024,when the file size
was beyond page size,the error must emerge.
       I think it is possible that I used the zlib
which is used in kernel 3.x ,but the kernel  I used is
2.x,but I didn't sure.
       Could you explain it? Thanks
