I am trying to use crash utility to modify a kernel memory from 2 to 0, but I hit an error like this,
`crash> rd ffffffffc0704310ffffffffc0704310: 0000000000000002 ........crash>crash> wr -k ffffffffc0704310 0wr: cannot write to /proc/kcore`
Is it possible to modify kernel memory with crash in live kernel debugging mode? If so, what shall I do?
