The picture shows SLES 10SP2, not OpenSUSE 11.1. You do know that SLES/D != OpenSUSE?
Anyway it looks like some process would not die by the time / needed to be umounted. Maybe it was ZMD (arrgh, I still get nightmares about it). Anyway it’s not a serious issue.
Dunno, maybe you could modify the shutdown script to run ps or better still lsof if the umount failed to show you what’s still running. I don’t know if running ps or lsof will work when you have already started a shutdown and libraries are inaccessible. Maybe you need a statically linked version of ps or lsof. Boy it’s getting complicated.
I have found the guilty of my problem…
It is the new version of the package util-linux …
The problem was appeared after an update of this package
(this package contain a lot af commands as mount, umount, etc…)
When i downgrade this package the problem disapear…
I get this error message also with openSUSE 11.2 and newer Linux kernels. (The text is displayed in green colour now.)
