[linux-dvb] Re: 2.5.55 and today CVS: GREAT!!!

[Michael Hunold]

Hello Gregoire,

I think you know that 2.5.56 is out, and that there is a problem with
linux-dvb:

WARNING: /lib/modules/2.5.56/kernel/arch/i386/kernel/microcode.ko needs unknown symbol devfs_set_file_size
WARNING: /lib/modules/2.5.56/kernel/fs/nfsd/nfsd.ko needs unknown symbol hash_mem

By looking at these lines, you should not that not only the dvb drivers are affected... ;-)

I hope I didn't make something wrong again?

Nope. The "module-init-tools" (to be precise: depmod) have a bug -- modules with GPL exported symbols are not handled correctly. The dependencies do *not* include dependencies to GPL modules, so nearly everything fails...

http://www.de.kernel.org/pub/linux/kernel/people/rusty/modules/

Get the latest "module-init-tools-0.9.7.tar.gz" and apply the patch that has been posted on lklm by Petr Vandrovec. (I attached it to this mail, too).

Thank you very much ;-)
	Gr�goire

CU
Michael.
