Xen users - Apr 2006 - Xen dom0 kernel, capi driver: unknown symbol

Hello,
Recently, I switched a server acting as a PSTN gateway to xen (3.0.2).
Unfortunately, I''ve some problems for loading the isdn card''s
module, it
look like a symbol is unknown to the kernel. The problem seem to be
introduced by xen as the corresponding vanilla kernel don''t cause any
troubles. (2.6.16).

Below the error from modprobe:
#modprobe fcpci
FATAL: Error inserting fcpci (/lib/modules/2.6.16-xen/extra/fcpci.ko):
Unknown symbol in module, or unknown parameter (see dmesg)

dmesg:
fcpci: module license ''Proprietary'' taints kernel.
fcpci: Unknown symbol force_evtchn_callback

It can be easily reproduced by downloading / compiling the last
''fritz''
drivers from avm.

Thanks

A quick grep of google says you''ve been bitten by the Richard Stallman
"free must be free and nothing but free" bug.

Basically it seems you''re using a module that is not GPL and the kernel
is objecting.

Thanks for your reply,
I don''t want to enter in a discussion related to softwares''
licenses but
just asking for help. I''m on this problem since some days now,
I''ve looked
for alternatives, like using non-prorietary drivers (mISDN code) but none
seem to be enough stable at the moment (experienced kernel oops, ...).

The kernel is objecting (warning the user about being tainted after loading 
the module because of licensing issues), but this is irrelevant for his 
problem. The module doesn''t fail to load because of the kernel warning,
but
because of the missing symbol.

And, basically, Richard Stallmans "free must be free and nothing but
free" is
not a bug, it''s a feature of the GPL. But this is a rather basic object
of
discussion, which I fear is inappropriate for this list. ;-)

Oh, and by the way, my (nearly vanilla, not Xen) 2.6.16-kernel doesn''t
define
the symbol you''re seeing (not even as a non-exported symbol):

modelnine@phoenix /usr/src/linux-2.6.16-gentoo-r2 $ 
grep -R "force_evtchn_callback" *
modelnine@phoenix /usr/src/linux-2.6.16-gentoo-r2 $

So, I guess that the drivers don''t work with 2.6.16, and that
it''s up to AVM
to offer updated drivers.

The ''famous'' symbol has been introduced in the xen kernel and
is
present on a large number of modules.
I''ve no reference about it on the original drivers'' sources.

I think the question is ''why it''s reported as unknown when
anothers
modules used it and are loaded without any problems?''.
Unfortunately I can''t answer to this question by myself it''s
why I''m
looking for help here.

Thanks
