Interesting. For which cmdline exactly?
"cygcheck -s -v -r > cygcheck.out" also please, since this is the first
time I heard it on a SMP.

I'm in the process of preparing a new procps release. Please try again with
that when it's announced.

That's unrelated, but interesting, because I got rooted yesterday on
some linux box (a new t0rnkit with some libsh), which had some libproc
hack (process hiding), which led to the same error message on the procps
utils.
"Unknown HZ value! (11) Assume 100"
At least it was very easy to fix without reinstall. ttyload got hijacked
(right after mingetty loading). rootkit in /usr/lib/libsh (hidden of
course). But he forgot to hijack lsof. So lsof|grep LISTEN showed the
intruder.
