2.6.22, without kernel patch, ps -ejH (shortened):
PID PGID SID TTY TIME CMD
2 0 0 ? 00:00:00 kthreadd
3 0 0 ? 00:00:00 migration/0
1 1 1 ? 00:00:00 init
821 821 821 ? 00:00:00 udevd
2228 2228 2228 ? 00:00:00 klogd
and `ps afx`:
PID TTY STAT TIME COMMAND
2 ? S< 0:00 [kthreadd]
3 ? S< 0:00 \_ [migration/0]
1 ? Ss 0:00 init [5]
821 ? S<s 0:00 /sbin/udevd --daemon
With procps patch: it's all thrown up again, possibly due to some
kernel patch that made it into 2.6.22.
(ps -ejH)
PID PGID SID TTY TIME CMD
2 0 0 ? 00:00:00 kthreadd
3 0 0 ? 00:00:00 migration/0
4 0 0 ? 00:00:00 ksoftirqd/0
1 1 1 ? 00:00:00 init
821 821 821 ? 00:00:00 udevd
2228 2228 2228 ? 00:00:00 klogd
(ps afx)
PID TTY STAT TIME COMMAND
2 ? S< 0:00 [kthreadd]
3 ? S< 0:00 [migration/0]
4 ? SN 0:00 [ksoftirqd/0]
1 ? Ss 0:00 init [5]
821 ? S<s 0:00 /sbin/udevd --daemon
2228 ? Ss 0:00 /sbin/klogd -c 5 -2 -x
(procps 3.2.7, the one used back when this thread was alive :^))

So does `ps afx` for me ;-)
