free free irq and Oops on cat /proc/interrupts
From: Manu Abraham
Date: Sat Sep 17 2005 - 05:06:51 EST
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
