I mean, if I faced any oops, which shows RIP is for example: RIP: 0010:[] {.text.lock.spinlock+0} then how can i locate the oops?it seems that .text.lock.spinlock is neither a function name, nor a variable name, so i am confused, who can help me out of here? Any advises is really really appreciated!
