Bug#351862: linux-image-2.6.15-1-k7: Kernel panic on joystick access (gameport/grip)

[Christian Henz <chrhenz@gmx.de>]

Package: linux-image-2.6.15-1-k7
Version: 2.6.15-4
Severity: important


When trying to access my gamepad, I get a kernel panic
when using 2.6.15. It always worked fine with earlier kernels
(just installed linux-image-2.6.15-1-k7 today).

I've got a Gravis gamepad (grip driver) connected to the
gameport of my onboard Via82xx soundcard. (Via KT133 chipset, 
Athlon C 1000 processor)

I wrote down most of the traceback that was dumped, but I probably 
made some errors copying it (especially the addresses...)

<0> Kernel panic - not syncing: Fatal exception in interrupt


I can reproduce the crash by running
$ jstest /dev/input/js0

If the joypad isn't connected, the crash doesn't occur.

Please let me know about any additional info you might need.

cheers,
Christian Henz
