Hello,
when my kernel autoloads module "wl" (package broadcom-sta) the following message appears:

A similar message appears when loading the "fuse" kernel module.
What I did up to now:
- recompile the system with emerge -ave system
- Restored a previous working kernel
I can't find out what's wrong. The system works without a problem when I'm not trying to load a kernel module.

Hi koschi,
I have some questions:- did you try to re-emerge broadcom-sta ?
- did you try : modules-rebuild rebuild (from sys-kernel/module-rebuild) ?
Good luck :]

Yes, but didn't work.

Maybe "modprobe" is broken? Which package do I have to re-merge?

Hi again,
sorry, I don't have anymore ideas; this problem is quite weird.
Modprobe is included in module-init-tools :
| Code: | $ equery b modprobe
* Searching for modprobe ...
sys-apps/module-init-tools-3.12-r1 (/sbin/modprobe) |
Or if you think that a hardware (or an agressive CFLAG) which is in fault, maybe you could try the binary version from the Gentoo tinderbox (here : module-init-tools-3.12-r1.tbz2).
Good luck !

Rebuilding module-init-tools also didn't work...
My cflags are "normal".

| The problem is the proprietary kernel module, not modprobe. Nothing you can do. |

| If the module is proprietary, then there's little you can do, other than asking whomever is in charge of producing it a new release that will work with your current kernel. That or change to a kernel version that works with the closed source module. |

This is not module related. The same happens when I'm trying to load the FUSE Kernel module.

I finally found it... My boot device wasn't mounted correctly so an old kernel was always booted 
That's why all modules didn't match the kernel.
THX to all for help.
