FATAL: Error inserting cloop : Invalid argument

[wsun013]

Hi all,

Before remastering my own knoppix, I am trying to extract the KNOPPIX file through the use of cloop.ko.

I am using Debian with kernel 2.6.16 patched with beyond3 patch set:
1. download the 2.6.16 source from http://www.kernel.org
2. patch it with the beyond3 patch from http://iphitus.loudas.com/archck.php
3. make-kpkg provided in Debian with gcc 4.1

gcc (GCC) 4.1.0 (Debian 4.1.0-1+b1)
Copyright (C) 2006 Free Software Foundation, Inc.

warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
4. install the generated deb file

Then I downloaded the cloop 2.02.1 source file from the debian's package page:
http://ftp.debian.org/debian/pool/main/c/cloop/cloop_2.02.1+eb.10.tar.gz

The cloop module was compiled without problems:

# make module

make[1]: Leaving directory `/usr/src/linux-2.6.16-beyond3'

and install without problem as well:


# make install-module
/usr/bin/make modules -C /lib/modules/2.6.16-beyond3-1-686/build M=/cvs3/cvs/modules/cloop-2.02.1+eb.10 KERNELRELEASE=2.6.16-beyond3-1-686

#depmod -a


However, when I tried to modprobe the module, it gave me a FATAL error:

# modprobe cloop
FATAL: Error inserting cloop (/lib/modules/2.6.16-beyond3-1-686/extra/cloop.ko): Invalid argument


From the dmesg:

"cloop": falsely claims to have parameter file

I thought that the argument ``file`` became optional long time ago. And I am wondering what is the cause of it ?
- Could it be the compiler ? Maybe gcc 4.1 is too new...but other modules (ndiswrapper, cdemu, cdfs, madwifi all ok...)
- Could it be the beyond patch ? The last 2.6.16 kernel I patched with beyond2 worked well with the cloop module

Thanks in advanced.
