The reasons is almost linked list on those function was broken. Ex:
linkedlist->next linkedlist->prev = NULL or set to invalid address.
In the situation SIGILL, the instruction pointer (NIP) is same as the
return address register (LR).
In later kernels, we have a list debugging option which lets you find
list corruptions earlier.
I'm not have much experience with linux kernel architecture, so I don't
know where I can focus on.
Currently, I'm suspecting these module are affected with this Oops:
Block I/O management and filesystem, some Wait Queue ? Is that correct ?
Or would you give me some suggestion what is the most suspicious ? or
some debugging option you told above ?
Thanks for your help,
