Hello All !
In my 2.6 kernel module I have a very simple code that in open method calls
ret = request_irq(pdev->irq, ppcnet_intr, SA_SHIRQ, DRIVER_NAME, dev);
assert(ret != 0);
and in release method calls
free_irq(pdev->irq, ppcnet_intr);
But after release method I see something like this in dmesg output:
Trying to free free IRQ8.
and after unloading module I see kernel oops and then when trying to
$ cat /proc/interrupts
I see just
Segmentation fault.
Where is my bug ? I would be happy to hear any tips or suggestions how to find
and fix it.
