But because -EINVAL was returned, the ftrace_bug() tried to report\nwhat was at the location of the ip address, and read it directly. This\ncaused the machine to panic, as the ip was not pointing to a valid memory\naddress.\n\nInstead, read the ip address with copy_from_kernel_nofault() to safely\naccess the memory, and if it faults, report that the address faulted,\notherwise report what was in that location."
