Hello dear Kernel People,
I have a problem with my gameport, it uses the ns558 driver, the module gets
loaded via hotplug/udev at boot, but the gameport gets deactivated somehow.
I have this Problem for a long time now, and my solution always was rmmod the
module and load it again after that the gameport is working.
But now i have 2.6.13-rc5 with debug stuff turned on and noticed that:
#rmmod ns558
Speicherzugriffsfehler <-- Segfault
This is from dmesg:
kobject_hotplug: /sbin/hotplug input seq=393 HOME=/

However after modprobe ns558 the gameport works and rmmod isn't possible
anymore:

Output of scripts/ver_linux follows(note the nvidia module, i have loaded it
after the oops so no problem, right?)
If some fields are empty or look unusual you may have an old version.
Compare to the current minimal requirements in Documentation/Changes.

Please take this up with the input guys, I'm guessing it shouldn't
happen in the first place, but regarding this bug look at the bottom.
