Subject: 2.5.59 Oops with insmod aironet4500_proc

Hi,

When I try to insmod aironet4500_proc, I get an Oops. The driver
itself is buildin (pci).

Kernel (2.5.59) is build with gcc (GCC) 3.2.2 20030131 (Debian prerelease)

module-init-tools version 0.9.9

Is there more info I should provide?

Can this have something to do with my patch for aironet4500_core.c ?
(I don't think so, but still ..)

Looks like you need the following patch (or moreal equiv).

Hope this helps!
Rusty.

Hi Rusty,

Sorry for the delay. A pentium 133 compiles as fast as you would expect
it to.

Your patch fixes my oops-on-insmod. Of course you knew this already,
didn't you ;-)

Thank you.
