doesn't matter! even with correct System.map file I get only empty WCHAN fields
with 2.2.0-final too:
# ps lp 1
FLAGS UID PID PPID PRI NI SIZE RSS WCHAN STA TTY TIME COMMAND
100 0 1 0 0 0 824 64 S ? 0:04 init [2]
^^^^^^^
with strace clearly showing that it's using the correct map:
open("/boot/System.map-2.2.0-final", O_RDONLY) = 3
