Hi,
Can somebody give me a pointer as to what i am possibly doing wrong.
The module loads fine.. Attached dmesg and stat [1]
The module unloads fine.. But i get a "free free IRQ" on free_irq()..
Attached dmesg [2]
I do a cat /proc/interrupts [5].. I get an Oops.. Attached dmesg [3] & [4]
I am trying to build it on a 2.6.13 kernel.
Thanks,
Manu

The last arg of request_irq and free_irq has to match - it is the id
that distinguishes different users of the same irq. As there never
was a request_irq with pdev you get that error on free_irq.
The module unload still takes place. So trying to cat /proc/interrupts
later on will stumble over the still installed handler with the mantis
id - unfortunately, the driver (and especially DRIVER_NAME) is no longer
in memory ...
