I cc'ed the btrfs-mailing list.

can't be loaded because of a unknown symbol crc32c (of course I added btrfs to 
the module file of initramfs-tools)
[...]

The list of btrfs dependencies is

$ cat /etc/initramfs-tools/modules
[..]
zlib_deflate
crc32c
libcrc32c
btrfs


I discovered that after a lot of tests...

And for what matters, on my fedora laptop (yes the root fs is btrfs)  the 
hibernation seems to work; even tough after the resume an error message 
appeared.
