Since kernel 2.6.26 fcdsl doesn't compile anymore. Very likely due to changes to block closed source applications from accessing GPL-only code in the kernel.

well, I have a simple solution for this problem. But I have to check first, if it is ok to do so. I want to use the "bindist" USE-Flag for (de)activating a small Patch, which replaces the propritary module license with a (fake) GPL-License. I guess it is ok to do so, as long as you don't spread this module (i.e. runs only on your computer).

If you change them to find_task_by_vid it will build and load just fine. I've done that on fcdsl2. But i'm facing a system freeze in the very moment pppd is trying to bring up a DSL connection (even sys-rq magic doesn't work). It smells like the BKL pushdown is to blame here (in ppp_generic, ppp_async or capi itself) but it could also be my config for 2.6.26... I'll try digging deeper into this with a debugging and KGDB enabled kernel over the next few days... Marc
Abandoned upstream. Won't work with current kernels. Closed Source.
