On openSUSE machine (non-working):
idose:~ # od -c /proc/2/cmdline
0000000
idose:~ # head /proc/2/status
Name:    kthreadd
State:    S (sleeping)
Tgid:    2
Pid:    2
PPid:    0

On my Gentoo machine (working):
psicose ~ # od -c /proc/2/cmdline
0000000
psicose ~ # head /proc/2/status
Name:    kthreadd
State:    S (sleeping)
Tgid:    2

I tried getting the hrSWRunPath for a bunch of other processes and it seems
on the openSUSE build it fails consistently on any kernel process (those
displayed as [foo] in ps output). I installed the exact same version of
net-snmp (5.4.2.1) on one of our Gentoo machines and it works fine. I think
that narrows it down to either some kind of configuration problem with the
openSUSE 11.1 distro, or something wrong with the way they built their
package.
