How did you generate it (with module-init-tools or with kmod)? Could
you attach your /lib/modules/3.0mamba/modules.dep ?

One thing you could try is to compile kmod with debug enabled
(--enable-configure flag), and run modprobe like below:

KMOD_LOG=8 modprobe -v squashfs

Then send the log.

Please, send also the output of "modinfo squashfs" (or "modinfo
/lib/modules/3.0mamba/kernel/fs/squashfs/squashfs.ko" if it doesn't
work).

What's the output of "uname -r"?

No problem, I'm CC'ing the mailing list so the email is properly archived.
