After going through the thread that you mentioned I moved to the latest one. But still the crash happens for me. Also I don't have iptables running in my system. And another thing is that, my kernel module always stops when it is trying to acquire a spinlock (spin_lock_irqsave) which is shared with code in the ISR. Is there any way to see the information about the lock, like who is holding the lock?? Does this give some insight into my actual problem?
